statsmodels.stats.proportion.proportions_chisquare_allpairs(count, nobs, multitest_method='hs') [source]

chisquare test of proportions for all pairs of k samples

Performs a chisquare test for proportions for all pairwise comparisons. The alternative is two-sided

Parameters:

count : integer or array_like the number of successes in nobs trials. nobs : integer the number of trials or observations. prop : float, optional The probability of success under the null hypothesis, 0 <= prop <= 1. The default value is prop = 0.5 multitest_method : string This chooses the method for the multiple testing p-value correction, that is used as default in the results. It can be any method that is available in multipletesting. The default is Holm-Sidak ?hs?.

Returns:

result : AllPairsResults instance The returned results instance has several statistics, such as p-values, attached, and additional methods for using a non-default multitest_method.

Notes

Yates continuity correction is not available.
