)[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{
int
, array_like} the number of successes in nobs trials.
- nobs
int
the number of trials or observations.
- multitest_method
str
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
