Objet : st: RE: Plots : Gamma density
-gammafit- and -pgamma- are user-written
commands for two-parameter gamma distributions
from SSC.
You don't say what p1 is here, perhaps
a typo for x1.
However, don't use the -fraction- option. The
defaulty -density- option for -histogram-
gives the natural scale for comparing with
a superimposed density function.
