The package provides the\nasymptotic chi-squared reference and parametric bootstrap\np-values for reliable finite-sample inference, covering the\nWeibull, Frechet, Gamma, Inverse-Gamma, Log-Normal, and\nLog-Logistic families. It also provides three diagnostic\ndiagrams (log-cumulant, kurtosis-skewness, and\ncoefficient-of-variation) with bootstrap concentration\nellipses, in the spirit of moment-ratio diagrams.
