Tree-Based Varying Coefficient Regression for Generalized Linear and Ordinal Mixed Models
Overview
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) doi:10.18637/jss.v080.i06.
- Fixed incorrect ordering in the variance-covariance matrix for adjacent category models. Affected only this model in previous package versions.
- Improved simulate() method for 'olmm' objects. Added a new argument 'ranef.simulate' to explicitely specify whether random effects should be simulated. The change results a slightly different behaviour compared to earlier versions. First, random effects are now simulated by default because of the default 'ranef.simulate = TRUE'. Second, if argument 'ranef = TRUE' is combined with 'ranef.simulate = FALSE', then random effects of new subjects are set to 0, which is consistent with the behaviour of the 'predict.olmm' function and the new argument terminology.
- Added option for running likelihood ratio tests for models fitted with olmm() using parametric bootstrap. See the anova() method for olmm().

- Added new function olmm_overwritePar() for overwriting coefficients of models fitted with olmm() objects, including automatically updating the likelihood and estimates for random effects. This function may be interesting for advanced bootstrap procedures.
- Added files Makevars and Makevars.win (essentially to improve compilation of C code in Windows)
