class statsmodels.sandbox.stats.multicomp.MultiComparison(data, groups, group_order=None)[source]

Tests for multiple comparisons

Parameters:

data : array

groups : array

group labels corresponding to each data point

group_order : list of strings, optional

Methods

allpairtest(testfunc[, alpha, method, pvalidx]) run a pairwise test on all pairs with multiple test correction
getranks() convert data to rankdata and attach
