%description
Generates tie-free progressive Type-II censored samples from discrete
distributions and user-specified discrete probability mass functions (PMF)
or cumulative distribution functions (CDF). Provides maximum likelihood
estimation (MLE), Bayesian estimation via Markov chain Monte Carlo (MCMC)
Metropolis-within-Gibbs sampling, likelihood-based parametric bootstrap
goodness-of-fit (GOF) tests, profile log-likelihood diagnostics, and
discrete survival and probability calculations. Methods are based on Ahmad
and Mansour (2026) <doi:10.1155/jom/3657078>, Balakrishnan and Dembinska
(2008) <doi:10.1016/j.jspi.2007.02.006>, Joe and Zhu (2005)
<doi:10.1002/bimj.200410102>, and Balakrishnan and Aggarwala (2000,
ISBN:978-1-4612-1334-5).
