Overview

About

Maintained by Osvaldo MartinCRAN page ↗GitHub ↗Website ↗Issues ↗

Performs projection predictive feature selection for generalized linear models (Piironen, Paasiniemi, and Vehtari, 2020, doi:10.1214/20-EJS1711) with or without multilevel or additive terms (Catalina, Bürkner, and Vehtari, 2022, https://proceedings.mlr.press/v151/catalina22a.html), for some ordinal and nominal regression models (Weber, Glass, and Vehtari, 2025, doi:10.1007/s00180-024-01506-0), and for many other regression models (using the latent projection by Catalina, Bürkner, and Vehtari, 2021, doi:10.48550/arXiv.2109.04702, which can also be applied to most of the former models). The package is compatible with the 'rstanarm' and 'brms' packages, but other reference models can also be used. See the vignettes and the documentation for more information and examples.

Changes in 2.11.0

Major changes

Minor changes

Added proj_epred(), which is essentially a wrapper around proj_linpred() with transform = TRUE. (GitHub: #559, #560)

Bug fixes and maintenance

Fixed bug in cv_varsel() with cv_method = "kfold": Submodels were incorrectly scored with the full data from the reference model family instead of the correct fold's one, which matters for the latent projection. (GitHub: #567, #568)
Tests: Adapt to version 0.9.15 of package mclogit (GitHub: #552)
Docs: Fix links to summary() generic (GitHub: #553)
Tests: Adapt tests to testthat v3.3.0 (GitHub: #554)
Use relative fontsize for model size numbers (GitHub: #555,#556)
Remove seemingly outdated lme4 note (GitHub: #558)
Add AI contribution policy (GitHub: #561)
Minor maintenance updates (GitHub: #562)

From NEWS.md in the release

Install

R (CRAN)pak (dev)Ubuntu (r2u)Fedora (COPR)openSUSE (OBS)

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

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

if (!requireNamespace("pak", quietly = TRUE))
  install.packages("pak", repos = "https://cloud.r-project.org/")
pak::pak("stan-dev/projpred")

Development version from stan-dev/projpred. Installs pak first if it is not already available.

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-projpred

Fast Ubuntu binaries via r2u (no compilation). The cranapt setup runs once and is skipped when it is already enabled. We list this channel from recorded r2u download activity rather than from a live index of the repository, so treat it as last known rather than guaranteed.

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

# enable the iucar/cran COPR if it is not already present, then install
ls /etc/yum.repos.d/*iucar*cran*.repo >/dev/null 2>&1 \
  || sudo dnf copr enable -y iucar/cran
sudo dnf install -y R-CRAN-projpred

RPMs from the iucar/cran COPR, rebuilt from CRAN.

For install.packages() integration in R, also: sudo dnf install R-CoprManager

# 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-projpred

RPMs auto-built from CRAN on openSUSE OBS (Tumbleweed). We list this channel from recorded autoCRAN download activity rather than from a live index of the repository, so treat it as last known rather than guaranteed.
