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 isprop = 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
