Performs a chisquare test for proportions for all pairwise comparisons. The alternative is two-sided
- Parameters:
- count{
int, array_like} the number of successes in nobs trials.
- nobs
int 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

- Returns:
- result
AllPairsResultsinstance The returned results instance has several statistics, such as p-values, attached, and additional methods for using a non-default
multitest_method.
