Implements the novel testing approach by Janitza et al.(2015) http://nbn-resolving.de/urn/resolver.pl?urn=nbn:de:bvb:19-epub-25587-4 for the permutation variable importance measure in a random forest and the PIMP-algorithm by Altmann et al.(2010) doi:10.1093/bioinformatics/btq134. Janitza et al.(2015) http://nbn-resolving.de/urn/resolver.pl?urn=nbn:de:bvb:19-epub-25587-4 do not use the "standard" permutation variable importance but the cross-validated permutation variable importance for the novel test approach. The cross-validated permutation variable importance is not based on the out-of-bag observations but uses a similar strategy which is inspired by the cross-validation procedure. The novel test approach can be applied for classification trees as well as for regression trees. However, the use of the novel testing approach has not been tested for regression trees so far, so this routine is meant for the expert user only and its current state is rather experimental.

Install

R (CRAN)Ubuntu (r2u)openSUSE (OBS)

install.packages("vita", repos = "https://cloud.r-project.org/")

Installs the current CRAN release. Prebuilt binaries on Windows and macOS.

Release

# enable cranapt (r2u) if it is not already set up, then install
grep -rqs r2u.stat.illinois.edu /etc/apt/sources.list /etc/apt/sources.list.d/ \
  || curl -fsSL https://raw.githubusercontent.com/eddelbuettel/r2u/master/inst/scripts/add_cranapt_noble.sh | sudo bash
sudo apt install -y r-cran-vita

Fast Ubuntu binaries via r2u (no compilation). The cranapt setup runs once and is skipped when it is already enabled.

bspm (used by r2u) also needs make: sudo apt install make

# add the autoCRAN OBS repo (Tumbleweed) if it is missing, then install
zypper -q lr | grep -qi autoCRAN \
  || sudo zypper addrepo https://download.opensuse.org/repositories/devel:/languages:/R:/autoCRAN/openSUSE_Tumbleweed/devel:languages:R:autoCRAN.repo
sudo zypper install -y R-vita

RPMs auto-built from CRAN on openSUSE OBS (Tumbleweed).
