This workshop provides an applied overview of principles and methods for longitudinal data analysis, with hands-on examples in R. Topics include types of longitudinal data, data manipulation and visualization, statistical methods for longitudinal analysis (including mixed-effects models and structural equation models), longitudinal measurement invariance, handling missing data, and separating within-person and between-person effects. Participants are encouraged to bring a laptop with R and RStudio installed for interactive exercises. This workshop is intended for participants with experience using R and RStudio. Prior experience with longitudinal data analysis, though helpful, is not required.

Isaac Petersen, associate professor in Psychological and Brain Sciences and CSSI researcher affiliate, will run the workshop.
