vcrpart (version 1.0-7)

Tree-Based Varying Coefficient Regression for Generalized Linear and Ordinal Mixed Models

Description

Recursive partitioning for varying coefficient generalized linear models and ordinal linear mixed models. Special features are coefficient-wise partitioning, non-varying coefficients and partitioning of time-varying variables in longitudinal regression. A description of a part of this package was published by Burgin and Ritschard (2017) .
