RTI International Researchers to Present Statistical Advances at International Conference

Media Contacts

RESEARCH TRIANGLE PARK, N.C. -- RTI International researchers will present statistical advances and research innovations at the world’s largest annual gathering of statisticians.

The presentations are part of the American Statistical Association's 2007 Joint Statistical Meetings, taking place July 29 – August 2 in Salt Lake City.

RTI's leading statisticians will present 18 papers and poster sessions to more than 5,000 attendees during the event. Many of those presentations will highlight efforts by RTI statisticians and epidemiologists to improve statistical methodology as well as public health.

RTI has six statisticians recognized as American Statistical Association Fellows, including the association’s 2008 president-elect, Sally Morton.

Presentations at the conference by RTI statisticians will include:

  • The Cumulative Distribution Function Adjustment Method Applied to Small Area Estimates of Serious Psychological Distress in the National Survey on Drug Use and Health
  • Expedient Small-Area Estimation via Proportional Odds Ratio Log-Linear Models
  • Designing Longitudinal Studies of Mobile Populations Such as Military Populations
  • An Additive Model for a Heavily Right-Skewed Outcome
  • Can Study Design Influence Substantive Survey Results?
  • Comparing the Coverage of a Household Sampling Frame Based on Mailing Addresses to a Frame Based on Field Enumeration
  • Patterns of Nonresponse for Key Questions in NSDUH and Implications for Imputation
  • Longitudinal Data Analysis Using SUDAAN
  • Evaluation of the Current Weighting Method for the BRFSS
  • The Impact of Incentives on Survey Participation and Reports of Intimate Partner and Sexual Violence
  • Comparison of the Five Test Statistics Currently Available in the SUDAAN Modeling Procedures
  • Combining RDD and Web Panel Surveys
  • Computer Tech Workshop: New Features for Clustered and Survey Data Analysis in SUDAAN Release 9.0.3
  • The Role of the Statistician in Biomedical Research: Scientist, Shoe Clerk, or Hired Gun
  • Assessing Baseline and Post-Baseline Effects in Repeated Measures Data Analyses: An Example Using Smoking Cessation Data
  • Setting Precision Requirements for Estimating Proportions
  • Using Interviewer Observations to Improve Nonresponse Adjustments: NES 2004
  • Simulation Study Comparing Inverse Probability of Treatment Weighted Estimator and Multiple Regression Model

RTI also will also showcase the SUDAAN® statistical software package developed by researchers at RTI that provides both descriptive and modeling procedures for analyzing survey and other correlated data encountered in epidemiological studies, clinical trials, experimental studies and longitudinal studies.
