Package: diversityForest Type: Package Title: Innovative Complex Split Procedures in Random Forests Through Candidate Split Sampling Version: 0.6.0 Date: 2025-05-03 Authors@R: c(person("Roman", "Hornung", role = c("aut", "cre"), email = "hornung@ibe.med.uni-muenchen.de"), person("Marvin N.", "Wright", role = c("ctb", "cph"))) Maintainer: Roman Hornung Description: Implementation of three methods based on the diversity forest (DF) algorithm (Hornung, 2022, ), a split-finding approach that enables complex split procedures in random forests. The package includes: 1. Interaction forests (IFs) (Hornung & Boulesteix, 2022, ): Model quantitative and qualitative interaction effects using bivariable splitting. Come with the Effect Importance Measure (EIM), which can be used to identify variable pairs that have well-interpretable quantitative and qualitative interaction effects with high predictive relevance. 2. Two random forest-based variable importance measures (VIMs) for multi-class outcomes: the class-focused VIM, which ranks covariates by their ability to distinguish individual outcome classes from the others, and the discriminatory VIM, which measures overall covariate influence irrespective of class-specific relevance. 3. The basic form of diversity forests that uses conventional univariable, binary splitting (Hornung, 2022). Except for the multi-class VIMs, all methods support categorical, metric, and survival outcomes. The package includes visualization tools for interpreting the identified covariate effects. Built as a fork of the 'ranger' R package (main author: Marvin N. Wright), which implements random forests using an efficient C++ implementation.
