About

Maintained by Shikhar TyagiFirst published 2026-08-081 releasesCRAN page ↗

Implements the Expectation-Maximization (EM) algorithm of Dempster, Laird, and Rubin (1977) doi:10.1111/j.2517-6161.1977.tb01600.x for parameter estimation under progressive Type-II censored data (Balakrishnan and Aggarwala (2000) doi:10.1007/978-1-4612-1186-0) and computes Generalized Process Capability Indices (GPCIs). Uses the 'UniCensorEM' package for EM estimation. Supports classical and generalized capability indices including Cpy (Maiti et al. (2010) doi:10.1080/16843703.2010.11673233), Cp, Cpk, Cpu, Cpl, Cpm, Cpmk, Spmk (Dey and Saha (2019) doi:10.1007/s41872-019-00081-4), CpTk (Saha et al. (2018) doi:10.1080/21681015.2018.1437793), Cpc, CNpmc (Alotaibi et al. (2022) doi:10.1155/2022/3135264), CNpmkc (Saha et al. (2024) doi:10.1142/S021853932450013X), and CNpk (Saha et al. (2022) doi:10.1080/02664763.2021.1971632). Computes point estimates, bias, mean squared error, risk, Heidelberger and Welch convergence diagnostics, convergence probability, and bootstrap confidence intervals at 90 percent, 95 percent, and 99 percent levels. Accommodates user-defined probability density or mass functions, cumulative distribution functions, and survival functions.

Install

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

install.packages("gpciEMprogII", 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-gpciEMprogII

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-gpciEMprogII

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