StressCensoR: Generalized Stress-Strength Reliability Estimation Under
Censoring Schemes
Generalized framework for data generation, Maximum Likelihood Estimation,
and Bayesian estimation of stress-strength reliability R = P(Y < X) for arbitrary continuous
distributions under censoring schemes based on Chapter 9 of 'Balakrishnan', 'Cramer',
and 'Kundu' (2023) <ISBN:978-0-12-398387-9>. Users provide probability density functions,
cumulative distribution functions, survival functions, support bounds, parameter ranges,
and sample sizes. Implements data generation under Type-I, Type-II, progressive
Type-II, Type-I hybrid, Type-II hybrid, generalized hybrid, progressive hybrid, joint, block
random, middle, and truncation censoring schemes, accompanied by diagnostic histograms, dot
plots, and autocorrelation plots. Maximum Likelihood Estimation supports optimization routines
including 'Newton-Raphson', 'Broyden'-'Fletcher'-'Goldfarb'-'Shanno' ('BFGS'), 'BFGS' in R ('BFGSR'),
'Berndt'-'Hall'-'Hall'-'Hausman' ('BHHH'), Simulated Annealing ('SANN'), Conjugate Gradients ('CG'), and
'Nelder'-'Mead' ('NM'), returning summaries ('AIC', 'coef', 'logLik', 'nIter', 'stdEr', summary, 'vcov'). Bayesian
estimation of stress-strength reliability R = P(Y < X) is performed via Gibbs sampling,
Metropolis-Hastings algorithm, Importance Sampling, and 'Lindley' approximation (1980).
