Andrea - How many exact zeros do you have? This looks like a mixed
discrete-continuous distribution, requiring something like a
zero-inflated model. Also, do you have repeated measures; i.e. is there
a clustering variable involved here?

It is an Herfindahl index of concentration, it ranges from 0 to 1 (in
principle) : in my specific case:
Variable | Obs Mean Std. Dev. Min Max
-------------+--------------------------------------------------------
H | 213620 .0190621 .0920916 0 .6477536
