"""K-Sample Rank Tests and their Combinations.
Compares k samples using the Anderson-Darling test, Kruskal-Wallis type
tests with different rank score criteria, Steel's multiple comparison test,
and the Jonckheere-Terpstra (JT) test. It computes asymptotic, simulated or
(limited) exact P-values, all valid under randomization, with or without
ties, or conditionally under random sampling from populations, given the
observed tie pattern. Except for Steel's test and the JT test it also
combines these tests across several blocks of samples. Also analyzed are 2
x t contingency tables and their blocked combinations using the
Kruskal-Wallis criterion. Steel's test is inverted to provide simultaneous
confidence bounds for shift parameters. A plotting function compares tail
probabilities obtained under asymptotic approximation with those obtained
via simulation or exact calculations."""
