%description
Implements Bayesian Markov Chain Monte Carlo (MCMC) estimation using
Metropolis-Hastings within Gibbs sampler for Generalized Process
Capability Indices (GPCIs) under Hybrid Type-II censored lifetime data.
Supports classical and generalized capability indices including Cpy, Cp,
Cpk, Cpm, Cpmk, Spmk, CpTk, Cpc, CNp, CNpk, CNpm, CNpmk, CNpmc, and
CNpmkc. Calculates 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 coverage probabilities. Accommodates user-defined
probability density/mass functions, cumulative distribution functions, and
survival functions. Based on methods described in Childs et al. (2003)
