(count, nobs, value=None, multitest_method='hs', alternative='two-sided')[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 two-sided, larger or smaller.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’.alternative : string in [‘two-sided’, ‘smaller’, ‘larger’]
alternative hypothesis, which can be two-sided or either one of the one-sided tests.
Returns: result : AllPairsResults instance
The returned results instance has several statistics, such as p-values, attached, and additional methods for using a non-default

Yates continuity correction is not available.
