Hello everyone,

How can I test the difference between the variance of two proportions?

Best,

What exactly do you mean by that

With two independent group of Bernoulli trials, and testing

$$H_0: p_1(1 - p_1) = p_2(1 - p_2)$$?

Thanks a lot BGM for the reply! Could you please give me some links with the formulas for this test or suggest me a program able to run this test?

All the best,
Ale
