TvemPackage_development
Progress on an R package for time-varying effects modeling
MixTVEM
Supporting material for the manuscript "Modeling Intensive Longitudinal Data With Mixtures of Nonparametric Trajectories and Time-Varying Effects" by Dziak, Li, Tan, Shiffman & Shiyko, submitted to Psychological Methods. This code facilitates fitting of MixTVEMs (mixtures of time-varying effects models).
