Biostatistics short course: Group-Based Trajectory Modeling – An Overview and Recent Advances
Daniel S. Nagin, PhD, Carnegie Mellon, will provide an overview of group-based trajectory modeling (GBTM) with a focus on applications in medicine and epidemiology and discuss recent advances in this area. Registration required.
In this workshop I will provide a brief overview of group-based trajectory modeling (GBTM) with a focus on applications in medicine and epidemiology. I will then discuss more recent advances in GBTM. These include multi-trajectory modeling, a generalized model that accounts for non-random subject attrition, and the use of posterior probabilities of group membership to predict the course of biomarkers and other indicators of disease progression or a patient’s recovery from a medical procedure. No prior background in trajectory modeling or a programming language is required.
