Message from the Chair
By: William Pan, PhD, APHA Statistics Section Chair
Greetings and Happy New Year!
Let me start by thanking several people who have dedicated enormous amounts of time and energy to improving our section and being vigilant of our interests in APHA. With the help of Karl Peace, APHA’s Archivist, I reconstructed a list of all our elected positions from 1990 to 2010 (Chair, Secretary, Governing Councilors and Section Councilors). The list is impressive, with 68 people volunteering their time to help our section, nine of whom have held the same position at least twice. Marcia Testa and Janet Eyster have both been Secretaries twice, Frank Potter has been on the Governing Council twice and Steve Cohen, Paula Diehr, Janet Eyster, Dedun Ingram, Diane Makuc and Craig Turnbull have all served on the Section Council for at least two terms. This doesn’t include the many people who have volunteered in other ways such as on the Awards and Spiegelman Committees, Web- and Booth-master, Membership Chair and Action Board. Volunteering is the core of APHA, and we could not function as a Section without you – so keep up the great work!
One of the activities I engaged in to prepare as Chair was to read messages from past Chairs. Every Chair in the past decade has addressed the very low participation of our section members and the glaring question remains: How do we increase participation of the rest of our section members? Is there a disconnect between the way each of us perceives ourselves in the organizations/companies for whom we work and that of APHA? Does the Section fail to present itself as a mechanism of action for our personal and/or ideological goals? Are we disempowered due to miscommunication, either sending or receiving information? While time is likely the primary limiting factor, participation in Section leadership activities over the past 21 years is shockingly low, averaging around 5-10 percent per year. The fault likely lies within the Section in the realms of governance, communication and opportunities for action. However, it is also important to point out that volunteering requires a very small time commitment.
This is where I would like to kick off 2010, our 103rd year depending on how one counts. During the 2009 Annual Meeting, I mentioned several goals for our section that I would like to describe in greater detail below. These are in addition to our standard expectations of organizing the Annual Meeting, which is being completed by Karl Peace, and communicating APHA activities to our section members.
1. Remind People of Our Mission.
We have become a Section that is believed to be “only for statisticians,” and several people who would be excellent advocates of our mission to be “promoters of good statistical practice” are often turned off because of the perceived need to have a statistical degree. Our section will always be a majority of statisticians and other quantitative experts, but we need to correct this perceived image.
In fact, our section is historically rooted in demography – in the late 1800s, there was widespread recognition that no U.S. State knew with any accuracy its birth and death rates. In 1900, the Census Bureau lead by Cressy Wilbur, 1906-1914, undertook the development of an annual system to collect vital statistics data that would be able to produce comparable statistics on a national basis. The Bureau recognized that their objectives required cooperation from several organizations, including APHA. In 1906, Dr. Wilbur wrote a resolution to the Governing Board of APHA at the Mexico City Annual Meeting calling for the creation of a Vital Statistics Section. Our first chair, John Hurty, noted the importance of developing a valid vital statistics registration system in his inaugural address and broadly defined an important theme that has resonated in our section for nearly a century:
“Perhaps the most important work before us is the adoption of rules of statistical practice. This will, doubtless, be done with wisdom, and then comes the practical working of them, a matter which will be attended with difficulties; but no difficulties shall be allowed to discourage... We shall now proceed with intelligent and persistent energy... The Section on Vital Statistics of the American Public Health Association is now in Action. Let the battle proceed.”
John N. Hurty- APHA Statistics Section Inaugural Address
Winnipeg, Manitoba, APHA Annual Meeting, 2008
We need to remind other members of APHA that the Statistics Section exists to ensure public health science is conducted with statistical vigilance and that the policies endorsed by the organization should be supported by strong scientific evidence. That has been our calling since 1907.
2. Increasing Membership
As of December 2009, we had 420 members. Our goal is to increase membership by 10 percent. How will we do this? I believe the keys are: (1) Reiterating our resolution as “promoters of good statistical practice” in public health within our personal and professional networks; (2) Reach out to all organizations (industry, academia, government) that are affiliated with our section to post fliers that introduce and briefly describe our section. We will have finalized versions of information fliers describing our section very soon, which will be part of a large advertising campaign to boost knowledge of our section to potential future members; and (3) Recruit students from Schools of Public Health, particularly in departments of biostatistics, epidemiology and health economics where students begin to appreciate the importance of good statistical practice. The first two components are relatively easy, require little effort and alone will likely allow us to achieve our goal of recruiting 42 new members.
The recruitment of students is more important for the sustainability of the Section. Thus, I am proposing that we formally establish the Annual Student Research Competition through the formation of a Student Awards Committee. The goal will be to design this award such that it becomes one of the most prestigious honors in public health that students can win. Ideally, the competition would involve the top four student submissions being invited to present at the annual meeting with students receiving financial support to attend and the top student being awarded a plaque for their research achievements. Much of this is already done in an informal fashion – for example, many of the requirements are already outlined and Altarum Institute, SciMetrika, and STATA have all graciously donated prizes and money for the 2010 awardees. This is a great start. If you are interested in volunteering for the Student Awards Committee please contact me as soon as possible.
3. Social Networking and Volunteerism
The two most important events for our section over the past five years was our 100th Anniversary Celebration organized by Marcia Testa and the establishment of the multiple membership policy that was championed by Andy White. I personally know almost 10 new “secondary members” that joined our section simply because of the Anniversary party. This networking has strengthened our section, but we cannot stop there. Generation X is quickly adopting the social networking tools of Generation Y, who will be key recruiters of Generation Z (X+Y=Z … simple enough). Social networking tools include Facebook, LinkedIn, Twitter, ScienceStage, and more. A more complete list can be found on Wikipedia. These Web portals not only allow people to stay in touch with very little effort, they allow information to be shared quickly and efficiently. We have established a team to begin creating social networking sites for our Section that is being coordinated by Mike Baiocchi (email@example.com) and we have recruited a new Webmaster Katherine Lin (firstname.lastname@example.org), to help redesign our Web site. If you are interested in helping out, please contact Mike or Katherine. They have already created Statistics Section sites on Facebook and Twitter, so please check them out. Although we won’t reach the level of Ashton Kutcher, who has over 4 million Twitter followers, we can definitely bring the Statistics Section into the age of Web networking!
By working together we can increase membership, strengthen our section, and increase our influence in public health. These are three ambitious, yet achievable goals for 2010. As John Hurty said, “Let the battle proceed!”

Janet Eyster, outgoing Statistics Section Secretary, moved formally into “APHA retirement” after 35 years of membership. The Statistics Section would like to take this opportunity to thank Janet for her decades of services to the Statistics Section. Janet joined APHA in 1976 and has served in several elected Statistics and Governing officer positions. Most importantly, she served as the Statistics Section’s archivist and historian. Janet received her PhD in statistics from Michigan State University in 1977, and then went on to serve on the faculty there. In 2004, while a member of the Department of Epidemiology at Michigan State, she won the Statistics Section award. At the 2004 Annual Meeting, she was recognized for her dedication to the Statistics Section particularly for her “exemplary assistance in placing the Spiegelman Award on a sound footing, for her philanthropic work, and for her contributions to hierarchical statistical modeling.”
During the Sunday meeting, the Section officers discussed their reports on membership and collaborations with American Statistical Association (James Leeper), Section Newsletter (Secretary-Elect Marcia Testa), Governing Council and APHA elections (Frank Potter and Amy Ferketich), Action Board and Section Awards (Ferketich), Spiegelman Awards (Leeper), Section Budget (James Leeper) and Statistics Section Booth and Web site (Larry Moulton).

Statistics Section Scientific Sessions
The Statistics Section scientific activities spanned a wide range of methodological topics including challenges with health insurance, drinking water and public health, environmental factors affecting children, lead in drinking water and children’s health and policy. However, what happened in Philadelphia does not have to stay in Philadelphia – at least with regard to the scientific meetings. If you missed the meetings, or just a particular presentation, you can always attend via the distance learning Webcast services that are offered by APHA. If you missed a particular Statistics Scientific Session, just go to:
Click on the Session you’re interested in, and it will bring you to the session agenda with a listing of each of the talks. You may listen via “Audio (mp3) recording” or “Multimedia recording”. It will ask you to select your playback mode, either “online” or “download” to your computer drive. Finally, you will be prompted to enter your last name and “personal subscription ID (PSI)”. Your PSI would have been e-mailed to you if you selected the e-learning option at registration; however, if you cannot find it you will have the option to have it sent to you again. Also, if you did not register for this service, you will be given the option to pay a fee to do so.
There were many members who participated in the scientific sections. We would like to spotlight one of the Section’s long-serving and valued Statistics Section members, Professor Daniel H. Freeman, Jr., PhD, a Past Statistics Section Chair (1997) who has also served as an officer in several positions. He’s currently a Statistics Section Councilor (2010-2012). Daniel Freeman is the Edgar Gnitzinger Distinguished Professorship in Aging; Director, Office of Biostatistics; Professor, Department of Preventive Medicine and Community Health, Division of Epidemiology and Biostatistics, University Texas Medical Branch at Galveston’s School of Medicine. He is also Professor, Department of Psychiatry and Behavioral Sciences. He previously served on the faculties of Yale University and Dartmouth Medical School. He has mentored dozens of master of public health students and doctoral students. His academic interests include aging, adolescent health and community based participatory research. The Section is honored to have him as a member.

2009 Spiegelman Award Winner
Rafael Irizarry, PhD, professor of biostatistics, Johns Hopkins Bloomberg School of Public Health, was this year’s Spiegelman Award Winner. Rafael received his PhD from the University of California at Berkeley in 1998. His outstanding research in bioinformatics and computational biology and academic accomplishments over the next 10 years propelled him to the rank of professor, and we honored him as this year’s award winner.
Dr. Irizarry’s research involves developing quantitative methods and software for genomics and epigenomics with a particular focus on microarrays and second generation sequencing. These technologies are used to measure diverse high genomic endpoints including genotype, chromosomal abnormalities including deletions/insertions, protein binding sites, methylation and alternative splicing.
He states that with these technologies, a number of steps are required to convert raw measures into the results relied upon by biologists and clinicians. These data manipulations influence the quality of the ultimate measurements and studies that rely upon them. He and his research team specialize in using modern statistical methodology to improve the accuracy and precision of these measurements, relative to ad-hoc procedures introduced by manufacturers of the technology.

2009 Lowell Reed Lecture
The 2009 Lowell Reed Lecture entitled “Measuring the HIV/AIDS Epidemic: Approaches and Challenges” was delivered by Ronald Brookmeyer, PhD, professor of biostatistics, Johns Hopkins Bloomberg School of Public Health and currently, professor, Department of Biostatistics, School of Public Health, University of California, Los Angeles. Dr. Brookmeyer’s research is at the interface of biostatistics and public health. A main theme of his work concerns statistical and quantitative approaches for measuring the health of populations through the development of statistical methods and models for tracking and forecasting health and disease. Dr. Brookmeyer has worked extensively on the development of methods for tracking the course of the global HIV/AIDS epidemic. He developed the back-calculation method for disease forecasting, and proposed statistical approaches for biomarker based methods for ascertaining current worldwide HIV incidence rates. He has also worked extensively on issues of biosecurity by developing models for tracking and containing anthrax outbreaks. His research interests in biostatistical methodology include survival analysis, epidemic models, epidemiological methods and multidimensional longitudinal data.
Prof. Ronald Brookmeyer remembers Prof. Stephen Lagakos, during the 2009 Lowell Reed Lecture
During his lecture Professor Brookmeyer reviewed methodologies that are currently being used to produce national and global HIV and AIDS statistics. He stated that the “statistics are changing.” He stated that the latest UN AIDS Worldwide estimates show that the number of people living with HIV infection decreased their previous estimate by 6 million people and that the incidence of HIV infection decreased by 42 percent. Dr. Brookmeyer noted that these changes in the statistics are not without some controversy. He noted that the day before his Lowell Reed Lecture, the UN AIDS Agency denied that it had previously inflated statistics to raise funds. To hear more about what has been deemed the controversial topic of the collision between epidemiology, statistics and political advocacy, go to Prof. Brookmeyer’s presentation using the APHA Web site links to the meeting presentations:

Remembering Professor Stephen Lagakos
At the beginning of his presentation, Prof. Brookmeyer remembered Prof. Stephen Lagakos, Department of Biostatistics, Harvard School of Public Health, who was killed tragically on Oct. 13, 2009, in a car crash in New Hampshire. Professor Lagakos was a world renowned researcher in the fight against HIV and AIDS.
Prof. Stephen Lagakos (1946 – 2009) is remembered for his enormous contributions to biostatistics and public health.
“Steve was a real giant in our field of biostatistics and public health. He made enormous contributions to survival analysis in clinical trials and in HIV methodology and HIV epidemiology. I had the great pleasure to serve with Steve. He chaired an Institute of Medicine Panel recently on HIV methodological issues. He was really a wonderful colleague, very insightful statistician. He has really been a role model for me my entire professional life so it is a really great loss, I think to the field. In fact, he was a Spiegelman Award winner as well. He won the Spiegelman Award in 1983.” Quote by Ronald Brookmeyer, PhD, Lowell Reed Lecture, November 2009

Special Annual Statistical Methodology Session Coordinated By Dr. Hongyu Zhao - “Challenges in Genomics Studies”
After the Lowell Reed Lecture, the Statistics Section sponsored the Special Annual Statistical Methodology Session entitled “Challenges in Genomics Studies.” The 2009 session was organized by the a previous Spiegelman Award Winner, Hongyu Zhao, PhD, professor of public health, Yale University. The objectives of the session were to describe the challenges of using genomics and proteomics technologies in public health research; to introduce novel statistical methods to address these challenges; and to demonstrate the usefulness of these methods in practical public health studies.
Prof. Zhao explained that during recent years there have been evolutions in molecular technologies that enable scientists to collect data at the genomics and proteomics levels. One example is the genome wide association study design where genetic information is collected at up to one million markers for thousands of individuals. This paradigm has led to the discoveries of hundreds of chromosomal regions affecting risks for dozens of common diseases in the past several years. However, there are significant statistical challenges in the analysis and interpretation of these rich data. The session reviewed statistical issues arising in this context, introduced a number of novel statistical and computational methods, and outlined the power of statistical thinking in analyzing these very high dimensional data.
The speakers and talks were: Mitchell Gail, MD, PhD, “Value of adding single nucleotide polymorphism data to a model that predicts breast cancer risk”; Xihong Lin, “Statistical Issues and Challenges in Analyzing High-throughput 'Omics Data”; and Jianqing Fan, “Variable selection in analysis of high-throughput data”.

CDC Tool for Assessing the Public Health Impact of Excessive Drinking
By: Mandy Stahre
With generous support from the Robert Wood Johnson Foundation, the Alcohol Program in the National Center for Chronic Disease Prevention and Health Promotion (NCCDPHP) at CDC has launched the Alcohol-Related Disease Impact (ARDI) software. ARDI is an online tool that allows users to assess deaths and Years of Potential Life Lost (YPLL) at the state and national levels due to excessive drinking (e.g., binge drinking). Currently, ARDI reports the average number of deaths and YPLL for 2001-2005. These outcomes are assessed for a total of 54 chronic (e.g., alcoholic liver disease and liver cancer) and acute (e.g., motor-vehicle traffic crashes and homicide) conditions that were judged by a panel of experts to be alcohol-related. Alcohol-attributable deaths and YPLL can also be assessed by age and sex, and for youth under 21 years of age. In addition to the data that are already available through ARDI, a custom data feature in the software allows users to upload data on deaths and the prevalence of alcohol consumption in a particular area (e.g., city or county) to generate local estimates of deaths and YPLL due to excessive drinking. This custom data is protected through a secure log-in, so only the users who entered it can access the results and generate custom reports. ARDI can be accessed through the CDC’s Alcohol and Public Health Web site at: www.cdc.gov/alcohol. Technical assistance is also available for users by contacting email@example.com.

Creating an Effective Graph
By: Xueyuan Wang
It’s easy to make histograms to compare a set of data by county. How about to show the population size of each county on the same chart using different colors? One way is to change each bar color based on the county's category you set up in Excel. I bet if you had to make 20 or 30 charts like I recently did, you would want to find a more efficient way to do this. I am happy to share with you my discovery of how to set up the bar colors automatically for each category.
The trick is to set up the data series in different columns so that your counties would be listed in each row. If the county has data in category column 1, you would then leave the other category columns blank. You can then sort the Excel file by category number to have a more organized Excel file. When you create a chart from this Excel file, it will have different sets of data in different colors on the chart. In the end you get the same results in less time.
If you have any questions or comments, contact Xueyuan Wang at Snow.Wang@usm.edu.

Improve Membership in the APHA Statistics Section
By: Karl E. Peace
Membership in the Statistics Section of APHA has dropped 25 percent over the last 14 years; from 558 in 1996 to 420 in 2009. With the expansion of public health, in academics and practice, one would think that there would have been an increase. The Statistics Section is the oldest section in APHA. It is time that we conducted a study to assess the reasons for the decline and to develop a program for increasing membership. I'm requesting volunteers who are willing to work on this project. If you’re interested, contact: Karl E. Peace, 2010 APHA Statistics Section Chair-Elect, at email@example.com. Thank you.

New Edited Book on 'Statistical Methods in Molecular Biology'
By: Madhu Mazumdar
Madhu Mazumdar is one of four editors on the new book, "Statistical Methods in Molecular Biology." While there is a wide selection of 'by experts, for experts’ books in statistics and molecular biology, there is a distinct need for a book that presents the basic principles of proper statistical analyses and progresses to more advanced statistical methods in response to rapidly developing technologies and methodologies in the field of molecular biology. "Statistical Methods in Molecular Biology" strives to fill that gap by covering basic and intermediate statistics that are useful for classical molecular biology settings and advanced statistical techniques that can be used to help solve problems commonly encountered in modern molecular biology studies, such as supervised and unsupervised learning, hidden Markov models, methods for manipulation and analysis of high-throughput microarray and proteomic data and methods for the synthesis of the available evidences.
This detailed volume offers molecular biologists a book in a progressive style where basic statistical methods are introduced and gradually elevated to an intermediate questions of interest to molecular biologists and the state-of-the-art statistical approaches to analyzing the data. As a volume in level, while providing statisticians knowledge of various biological data generated from the field of molecular biology, the types of the highly successful "Methods in Molecular Biology" series, this work provides the kind of meticulous descriptions and implementation advice for diverse topics that are crucial for getting optimal results. Comprehensive but convenient, "Statistical Methods in Molecular Biology" will aid students, scientists and researchers along the pathway from the beginning strategies to a deeper understanding of these vital systems of the data analysis and interpretation within one volume of the book.

Interested in Collaborating? UNICEF - Child Health in West Africa
By: David J. Fitch
I’ve been thinking about the Jan. 12, 2010 Lancet evaluation article by Jennifer Bryce et al on the 27 million dollar UNICEF child health effort in West Africa, which seems to have led to the decision to cancel the work. Efforts were made in areas of poor health, and the outcomes were similar to those from better off areas without UNICEF efforts, showing an unbelievably bad design. I’ve been thinking and came up with an article idea. If you’re interested in helping or have any comments or thoughts, contact: David J. Fitch at firstname.lastname@example.org. Thank you.

Predicting and Preventing Homicide: A Cost-Effective Empirical Approach from Infancy to Adulthood
By: Robert John Zagar
The entire February 2009 issue of Psychological Reports, all 377 pages, was devoted to a new math model of violence. As a result of this research, Robert John Zagar was appointed to Mayor Daley's Youth Violence Task Force. Multiple meetings resulted in a $60 million U.S. Justice Department grant to focus jobs and anger management on 38 homicide area high school high risk teens. This was featured in the Oct. 6 front page articles in the NY Times and Chicago Tribune that included interviews with Chicago Public Schools CEO Huberman. The accuracy of prediction of homicide as measured by area under the curve obtained with Shao's bootstrapped logistic regressions was .88-.98, improving earlier ROC's of .70-.76.
