%description
Implements stress-strength reliability models under a dependent framework,
where both stress and strength variables follow modified Weibull
distributions and their dependence is modeled using a Clayton copula
(Kizilaslan (2026) <doi:10.48550/arXiv.2604.12130>). The package provides
several estimation procedures for model parameters and the stress-strength
reliability R, including two-step maximum likelihood estimation (MLE),
least squares estimation (LSE), weighted least squares estimation (WLSE),
and maximum product of spacings (MPS). It also provides interval
estimation using asymptotic confidence intervals based on MLE and
bootstrap confidence intervals for all methods. In addition, functions are
included for parameter estimation of the modified Weibull distribution
(Lai et al. (2003) <doi:10.1109/TR.2002.805788>) and the two-parameter
Weibull distribution, along with utilities to compute their probability
density function, cumulative distribution function, quantile function, and
to generate random samples.
