probabilityderiv {MultNonParam} | R Documentation |
probabilityderiv
calculates derivatives probabilities of one variable exceeding another,
where the variables are independent, and with identical distributions except for a location shift, at the null hypothesis.
This calculation is useful for power of Mann-Whitney-Wilcoxon, Jonckheere-Terpstra, and Kruskal-Wallis testing.

Probabilities of particular families must be calculated analytically, and then differentiated.
The scalar derivative.
