Dear statalisters,

Is there any way to test equality of skewness across groups? whether
two samples are drawn from a uniform distribution?

I found several partial solutions - but what I actually need seems to
be something equivalent to -sdtest- applied to skewness instead of
variance.

Other partial solutions that I found is to use -sktest-. The problem
is that the test is applied to each group separately and not makes
comparison across groups

I also tried -ksmirnov-, but this test does not work very well on
small samples and it is not very helpful

I wonder if there is a better solution.

As always, your answers will be highly appreciated
