wei.series.md.c1.c2.c3: Estimating Reliability of Weibull Components in Series from Masked Data

R package implementing maximum likelihood estimation of Weibull component parameters in series systems from masked failure data. Implements the methodology from Towell (2023) 'Reliability Estimation in Series Systems'. Handles right-censored system lifetimes and masked component failure causes via candidate sets satisfying identifiability conditions. Provides log-likelihood, score, and Hessian functions along with multiple MLE solvers. Companion paper: https://doi.org/10.5281/zenodo.18615871
