Dunnett's many-to-one test of means against the control (the first group), with the pooled variance. Equivalent to
PMCMRplus::dunnettTest() in R. The p-values are the exact multivariate t probabilities (R approximates them by
randomised integration); two-sided, as in PMCMRplus, min(1, 2 P(max T_i >= |t|)).
