Dear Statalist.

I have a small sample of countries. I have two variables, X which is a continuous variable, and Y which is a dichotomous one. The problem is that my variable X is not normally distributed, so I cannot use point-biserial test, then I am looking for a non-parametric test. Reading the literature I have read about "Eta correlation test". However, I do not Know how to compute it in Stata. Any advise?

Thanks in advanced,
Ibai
