Hi Statalisters.

I have some continous data to work with. Some of the observations are
negative values. How to make appropiate statistics in Stata to deal
with this negative values? I want to be sure that the statistics are
correctly performed. I want to perform descriptive statistics and then
non-parametric statistics such as t-test's and Kruskal-Wallis.

I will appreciate, as always, your help.

Sincerely,
