Webinar: Biostatistics and Bioinformatics Seminar – ‘Integrating summary information from external studies with heterogeneous populations’

November 10, 2021, 12:00 pm to 1:00 pm

Presented by: Peisong Han, PhD, associate professor, Department of Biostatistics, School of Public Health, University of Michigan

About the presentation: It is common to have access to summary information from external studies. Such information can be useful in model building for an internal study of interest and can improve parameter estimation efficiency when incorporated. However, external studies may target populations different from the internal study, in which case an incorporation of the corresponding summary information may introduce estimation bias. We develop a method that selects the external studies whose target population is the same as the internal study and simultaneously incorporates their available information into estimation. The resulting estimator has the efficiency as if we knew which external studies target the same population and made use of information from those studies alone. The method is applied to a prostate cancer study to incorporate external summary information to improve parameter estimation.
