Optimization of conditional inference trees from the package 'party'
for classification and regression.
For optimization, the model space is searched for the best tree on the full sample by
means of repeated subsampling. Restrictions are allowed so that only trees are accepted
which do not include pre-specified uninterpretable split results (cf. Weihs & Buschfeld, 2021a).
The function PrInDT() represents the basic resampling loop for 2-class classification (cf. Weihs
& Buschfeld, 2021a). The function RePrInDT() (repeated PrInDT()) allows for repeated
applications of PrInDT() for different percentages of the observations of the large and the
small classes (cf. Weihs & Buschfeld, 2021c). The function NesPrInDT() (nested PrInDT())
allows for an extra layer of subsampling for a specific factor variable (cf. Weihs & Buschfeld,
2021b). The functions PrInDTMulev() and PrInDTMulab() deal with multilevel and multilabel
classification. In addition to these PrInDT() variants for classification, the function
PrInDTreg() has been developed for regression problems. Finally, the function PostPrInDT()
allows for a posterior analysis of the distribution of a specified variable in the terminal
nodes of a given tree.
In version 2, additionally structured sampling is implemented in functions PrInDTCstruc() and
PrInDTRstruc(). In these functions, repeated measurements data can be analyzed, too.
Moreover, multilabel 2-stage versions of classification and regression trees are
implemented in functions C2SPrInDT() and R2SPrInDT() as well as interdependent
multilabel models in functions SimCPrInDT() and SimRPrInDT(). Finally, for mixtures of
classification and regression models functions Mix2SPrInDT() and SimMixPrInDT() are
implemented. Most of these extensions of PrInDT are described in Buschfeld &
Weihs (2025Fc).
