%description
Evaluates Generalized Process Capability Indices (GPCIs) under Hybrid
Type-II censored lifetime data using Importance Sampling (Sampling
Importance Resampling, SIR). Implements Bayesian parameter estimation and
evaluates classical and generalized capability indices including Cpy, Cp,
Cpk, Cpu, Cpl, Cpm, Cpmk, Spmk, CpTk, Cpc, CNp, CNpk, CNpm, CNpmk, CNpmc,
CNpmkc, and Vannman's Cp(u,v) family. Computes initial maximum likelihood
estimates under Hybrid Type-II censoring, parameter MCMC chains, GPCI
posterior chains, posterior point estimates, bias, mean squared error
(MSE), Bayes risk, Highest Posterior Density (HPD) credible intervals at
90%%, 95%%, and 99%% levels, Heidelberger and Welch's MCMC convergence
diagnostics, and convergence probabilities. Accommodates user-defined
probability density/mass functions, cumulative distribution functions, and
survival functions. Goodness-of-fit testing for Hybrid Type-II censored
data is supported via 'gofPHCS'. Methods are based on Childs et al. (2003)
