Result of
test_proportions_2indep.- Parameters:
- statistic
float Test statistic, asymptotically normal distributed N(0, 1).
- pvalue
float p-value based on the normal distribution.
- compare{“diff”, “ratio”, “odds-ratio”}
Which comparison of the two proportions the test is for.
- method
str Method used to compute the test.
- diff
float Observed difference,
prop1 - prop2.- ratio
float Observed risk ratio,
prop1 / prop2.- odds_ratio
float Observed odds ratio.
- variance
float Estimated variance of the test statistic under the null hypothesis.
- alternative{‘two-sided’, ‘smaller’, ‘larger’}
The alternative hypothesis used for the test.
- value
float Value of the difference, risk ratio or odds ratio under the null hypothesis.
- prop1_null
floatorNone,optional Constrained estimate of the first proportion under the null hypothesis. Only set if
method="score", otherwise None.- prop2_null
floatorNone,optional Constrained estimate of the second proportion under the null hypothesis. Only set if
method="score", otherwise None.
