TTest

Student's and Welch's t-tests: independent, paired and one-sample.

Arrays in, a statistic and a p-value out; every entry point is static. Independent defaults to Variance.Welch, where scipy.stats.ttest_ind defaults to Student's equal_var=True — pooling is only correct when the two populations really share a variance, so the safer default costs a word at the call site rather than a wrong answer.
