Compares k samples using the AndersonDarling test, KruskalWallis type tests with different rank score criteria, Steel's multiple comparison test, and the JonckheereTerpstra (JT) test. It computes asymptotic, simulated or (limited) exact Pvalues, 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 KruskalWallis 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.
