An R package for testing goodness of fit: goft
Authors:E González-Estrada  J A Villaseñor
Institution:Colegio de Postgraduados, Texcoco, México
Abstract:This R package implements three types of goodness-of-fit tests for some widely used probability distributions where there are unknown parameters, namely tests based on data transformations, on the ratio of two estimators of a dispersion parameter, and correlation tests. Most of the considered tests have been proved to be powerful against a wide range of alternatives and some new ones are proposed here. The package's functionality is illustrated with several examples by using some data sets from the areas of environmental studies, biology and finance, among others.
Keywords:Tests of fit  hypothesis testing  Shapiro–Wilk test  Anderson–Darling test  correlation tests  data transformations  probability distributions
