statsmodels.sandbox.stats.multicomp.MultiComparison

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

Tests for multiple comparisons

Parameters
datandarray

independent data samples

groupsndarray

group labels corresponding to each data point

group_orderlist[str], optional

the desired order for the group mean results to be reported in. If not specified, results are reported in increasing order. If group_order does not contain all labels that are in groups, then only those observations are kept that have a label in group_order.

Methods

allpairtest(testfunc[, alpha, method, pvalidx])

run a pairwise test on all pairs with multiple test correction

getranks()

convert data to rankdata and attach

kruskal([pairs, multimethod])

pairwise comparison for kruskal-wallis test

tukeyhsd([alpha])

Tukey’s range test to compare means of all pairs of groups
