In hypothesis testing of mu1 and mu2 or sigma1^2 and sigma2^2, side is a parameter used to control two sided or one sided hypothesis testing. When inputting side = 0 (default), the function computes two sided hypothesis testing, and H1: mu1 != mu2 or H1: sigma1^2 != sigma2^2; when inputting. One and Two Samples Using Only an R Function In statistical hypothesis testing, a two-sample test is a test performed on the data of two random samples, each independently obtained from a different given population. The purpose of the test is to determine whether the difference between these two populations is statistically significant.
