- statsmodels.stats.proportion.proportions_chisquare_pairscontrol(count, nobs, value=None, multitest_method='hs', alternative='two-sided')¶
chisquare test of proportions for pairs of k samples compared to control
Performs a chisquare test for proportions for pairwise comparisons with a control (Dunnet’s test). The control is assumed to be the first element of
nobs. The alternative is two-sided, larger or smaller.

the number of trials or observations.
The probability of success under the null hypothesis, 0 <= prop <= 1. The default value is prop = 0.5
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’.
