Steel's many-to-one rank test in its normal approximation: the Mann-Whitney statistic of each group against the
control (the first group), each pair ranked on its own (midranks), standardised with the tie-corrected variance.
Equivalent to PMCMRplus::manyOneUTest() in R. The statistic is positive when the group ranks higher than the
control. With pAdjustMethod"single-step" (the default; at least three groups) the p-values are the exact
simultaneous normal probabilities (R approximates them by randomised integration).
