About

Maintained by Shikhar TyagiFirst published 2026-08-051 releasesCRAN page ↗

Implements generalized statistical point prediction and prediction intervals for future failure times under various hybrid censoring schemes. Supported censoring schemes include Type-I, Type-II, Generalized Type-I, Generalized Type-II, Unified, Progressive Type-I, and Progressive Type-II hybrid censoring schemes. Available prediction methods include Best Unbiased Predictor (BUP), Conditional Median Predictor (CMP), Maximum Likelihood Predictor (MLP), equal-tailed classical prediction intervals, Highest Conditional Density (HCD) prediction intervals, and Bayesian prediction intervals. Algorithms accept user-defined continuous probability density functions, cumulative distribution functions, quantile functions, or survival functions along with estimated parameter values. Methodological foundations are based on Balakrishnan, Cramer, and Kundu (2023, ISBN:978-0123983879), Shafay and Balakrishnan (2012) doi:10.1080/03610918.2011.579367 for Type-I hybrid censoring, Balakrishnan and Shafay (2012) doi:10.1080/03610926.2010.543300 for Type-II hybrid censoring, Shafay (2017) doi:10.1080/03610926.2016.1200093 for Generalized Type-I hybrid censoring, Shafay (2016) doi:10.1080/00949655.2015.1096361 for Generalized Type-II hybrid censoring, Mohie El-Din, Nagy, and Shafay (2017) doi:10.18576/jsap/060113 for Unified hybrid censoring, Ebrahimi (1992) doi:10.1109/24.126685, Valiollahi, Asgharzadeh, and Kundu (2017) doi:10.1214/15-BJPS302, and Asgharzadeh, Valiollahi, and Kundu (2015) doi:10.1080/00949655.2013.848451.

Install

R (CRAN)Fedora (COPR)openSUSE (OBS)

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

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

# 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-predHCS

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-predHCS

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