OLS (Ordinary Least Squares) regression is known to\nbe sensitive to outliers. A single outlying observation can\nchange the values of estimated parameters. LTS is a resistant\nestimator even the number of outliers is up to half of the\ndata. This package is for estimating the LTS parameters with\nlower bias and variance in a reasonable time. Version >=1.3\nincludes the function medmad for fast outlier detection in\nlinear regression.", "License": "GPL", "LazyLoad": "yes", "Packaged": { "Date": "2026-10-05 08:25:07 UTC", "User": "root" },
