A Simple R Package for Classical Parametric Statistical Tests and Confidence Intervals in Large Samples
Released May 10, 2018 by Pierre Lafaye de Micheaux
One and two sample mean and variance tests (differences and ratios) are considered. The test statistics are all expressed in the same form as the Student t-test, which facilitates their presentation in the classroom. This contribution also fills the gap of a robust (to non-normality) alternative to the chi-square single variance test for large samples, since no such procedure is implemented in standard statistical software.
