You may increase your chance to get an answer by:
1) choosing a title (and possibly, an informative one) for your e-mail
2) citing appropriate references fully
3) asking for a Stata- more than a statistics-related question (if you know the name of the "new tests" and tell us, it would help Statalist members to help you)
Having remarked that, I think -pescadf- from SSC may be what you asked for. If it's not, please read the Statalist FAQ before reposting.
