... Details of the Methods To Be Compared This section describes the methods to be compared. Three are based on measures of location: the usual Student’s t test, Welch’s (1938) test, and a generalization of Welch’s method derived by Yuen (1974) designed to test the hypothesis that two independent groups ...

... and failure are assumed to be 1/2 but could be any fixed probability. We’ll use p to denote the probability of success and q = 1 − p to be the probability of failure. For this example, let’s take a sequence of 6 Bernoulli trials, each with probability p of success. The sample space Ω has 26 = 64 ou ...
