proportions_chisquare_pairscontrol
(count, nobs, value=None, multitest_method='hs', alternative='twosided')[source]¶ 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
count
andnobs
. The alternative is twosided, larger or smaller. Parameters
 countinteger or array_like
the number of successes in nobs trials.
 nobsinteger
the number of trials or observations.
 propfloat, optional
The probability of success under the null hypothesis, 0 <= prop <= 1. The default value is prop = 0.5
 multitest_methodstring
This chooses the method for the multiple testing pvalue correction, that is used as default in the results. It can be any method that is available in
multipletesting
. The default is HolmSidak ‘hs’. alternativestring in [‘twosided’, ‘smaller’, ‘larger’]
alternative hypothesis, which can be twosided or either one of the onesided tests.
 Returns
 resultAllPairsResults instance
The returned results instance has several statistics, such as pvalues, attached, and additional methods for using a nondefault
multitest_method
.
