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

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

Return type:

AllPairsResults instance

Notes

Yates continuity correction is not available.
