Some improvements, namely trimmed\nmeans and Winsorized variances, and bootstrapping for\ncalculating an empirical critical value, have been added to the\nclassical formulation. The code departs from a previous SAS\nimplementation by L.M. Lix and H.J. Keselman, available at\n\nand published in Keselman, H.J., Wilcox, R.R., and Lix, L.M.\n(2003) .", "Version": "0.3.2", "Date": "2019-09-08", "Author": "Pablo J. Villacorta ", "Maintainer": "Pablo J.
