Description: 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).
    Methods and censoring schemes are described in
    'Balakrishnan', 'Cramer', and 'Kundu' (2023, ISBN:978-0-12-398387-9),
