Class StudentTTest


public class StudentTTest extends Object
Performs Students's 2-sample t-test. The null hypothesis is that the two data sets have equal mean. This test assumes equal variance between the two samples and does not assume equal sample size. For unequal variances, Welch's t-test should be used instead.
