How to perform F-test in R for checking equality-of-variance (homoscedasticity/heteroscedasticity) if raw data is not given?
In a typical two-sample problem scenario, I possess the sample mean, variance, and size, but not the raw data for samples drawn from two populations. I wish to perform the F-test to check equality of ...

I am interested in generating Gaussian mixture distributions as the null distributions for a series of two-sample test simulations. It is a well established fact that p-values follow a uniform ...

In practice we sometimes used a wisdom that two overlapping CIs for sample mean distribution meant we could not reject Hull hypothesis, to get a quick answer.
It looks though that this is a very raw ...
