class statsmodels.stats.proportion.Proportions2indepTestResult(statistic, pvalue, compare, method, diff, ratio, odds_ratio, variance, alternative, value, prop1_null=None, prop2_null=None)[source]#

Result of test_proportions_2indep.

Parameters:

statisticfloat: Test statistic, asymptotically normal distributed N(0, 1).
pvaluefloat: p-value based on the normal distribution.
compare{“diff”, “ratio”, “odds-ratio”}: Which comparison of the two proportions the test is for.
methodstr: Method used to compute the test.
difffloat: Observed difference, prop1 - prop2.
ratiofloat: Observed risk ratio, prop1 / prop2.
odds_ratiofloat: Observed odds ratio.
variancefloat: Estimated variance of the test statistic under the null hypothesis.
alternativestr: The alternative hypothesis used for the test.
valuefloat: Value of the difference, risk ratio or odds ratio under the null hypothesis.
prop1_nullfloat or None: Constrained estimate of the first proportion under the null hypothesis. Only set if method="score", otherwise None.
prop2_nullfloat or None: Constrained estimate of the second proportion under the null hypothesis. Only set if method="score", otherwise None.
