*PlotDensities[]* is not a standard built-in function and it does not
belong to the standard add-ons. So the question is, "What is
PlotDensities[] and where can one find it?

Does the functions/expressions model and estimate explicitly depends on
the variables mu and sigma?

P.S. Is the PlotDensities[] function you use the same as the one one can
find in Luke Froeb's "ML" package?
From the author's website;
Maximum Likelihood Estimation Software
* ML is a Mathematica 3.0 notebook and package. This is a set
of maximum likelihood estimation routines with a collection
of examples, including a multivariate logit with changing
choice set..
