%description
Provides methods for recursive partitioning based on the 'Graded Response
Model' ('GRM'), extending the 'MOB' algorithm from the 'partykit' package.
The package allows for fitting 'GRM' trees that partition the population
into homogeneous subgroups based on item response patterns and covariates.
Includes specialized plotting functions for visualizing 'GRM' trees with
different terminal node displays (threshold regions, parameter profiles,
and factor score distributions). For more details on the methods, see
