gpcihybridII: Generalized Process Capability Indices under Hybrid Type-II
Censoring
A comprehensive, generalized framework for computing, estimating,
and validating Generalized Process Capability Indices (GPCIs) under Hybrid
Type-II censored lifetime data. Supports user-supplied probability density or
mass functions (PDF/PMF), cumulative distribution functions (CDF), survival
functions (SF), and quantile functions. Parameter estimation under Hybrid
Type-II censoring is performed via Maximum Likelihood Estimation using the
'MleCensoR' package (Childs et al., 2003 <doi:10.1007/BF02517803>;
Balakrishnan & Kundu, 2013 <doi:10.1002/nav.21545>). Computes classical
and non-normal capability indices, including Cpy (Maiti et al., 2010
<doi:10.1080/16843703.2010.11673233>), Spmk (Dey & Saha, 2019
<doi:10.1007/s41872-019-00081-4>), CpTk (Saha et al., 2019), Cpc (Saha et al., 2022
<doi:10.1080/02664763.2021.1971632>), CNpmc (Alotaibi et al., 2022
<doi:10.1155/2022/3135264>), CNpmkc (Saha et al., 2024 <doi:10.1142/S021853932450013X>),
CNpk (Saha et al., 2018 <doi:10.1080/21681015.2018.1437793>), and Vannman's Cp(u,v)
family. Evaluates parametric and non-parametric bootstrap confidence intervals
at 90 percent, 95 percent, and 99 percent levels of significance using percentile,
normal, basic, BCa, BCp, and studentized bootstrap methods. Computes standard
errors, mean squared errors, and coverage probabilities for both distribution
parameters and capability indices. Integrates goodness-of-fit testing for
Hybrid Type-II censored data via the 'gofPHCS' package.
