%description
Computes Dunn's test (1964) for stochastic dominance and reports the
results among multiple pairwise comparisons after a Kruskal-Wallis test
for 0th-order stochastic dominance among k groups (Kruskal and Wallis,
1952). 'dunn.test' makes k(k-1)/2 multiple pairwise comparisons based on
Dunn's z-test-statistic approximations to the actual rank statistics. The
null hypothesis for each pairwise comparison is that the probability of
observing a randomly selected value from the first group that is larger
than a randomly selected value from the second group equals one half; this
null hypothesis corresponds to that of the Wilcoxon-Mann-Whitney rank-sum
test. Like the rank-sum test, if the data can be assumed to be continuous,
and the distributions are assumed identical except for a difference in
location, Dunn's test may be understood as a test for median difference
and for mean difference. 'dunn.test' accounts for tied ranks.
