Goodness-of-Fit Tests for Location-Scale Distributions via Lorenz Curve // Implements goodness-of-fit test statistics and graphical methods for symmetric and asymmetric location-scale distributions under progressive Type-II censoring using the modified Lorenz curve and ratio modified sample Lorenz curve, as proposed by Lee (2024) doi:10.3390/sym16020202. Also provides order statistics distance test statistics based on Pakyari and Balakrishnan (2013) doi:10.1080/00949655.2011.625424. Supports calculation of test statistics, Monte Carlo p-values, critical values, and L-plot visual diagnostics for complete and progressively Type-II censored data.
