Description: Implementation of the unity forest (UFO) framework (Hornung & Hapfelmeier, 2026,
  <doi:10.48550/arXiv.2601.07003>).
  UFOs are a random forest variant designed to better take covariates with purely
  interaction-based effects into account, including interactions for which none of the involved
  covariates exhibits a marginal effect.
  While this framework tends to improve discrimination and predictive accuracy compared
  to standard random forests, it also facilitates the identification and interpretation of
  (marginal or interactive) effects: In addition to the UFO algorithm for tree construction,
  the package includes the unity variable importance measure (unity VIM), which quantifies
  covariate effects under the conditions in which they are strongest - either marginally 
  or within subgroups defined by interactions - as well as covariate-representative tree
  roots (CRTRs) that provide interpretable visualizations of these conditions.
  Categorical and continuous outcomes are supported.
  This package is a fork of the R package 'ranger' (main author: Marvin N. Wright), which
  implements random forests using an efficient C++ backend.
