Regards, - Jean-Marc 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.. http://www2.owen.vanderbilt.edu/luke.froeb/software/Default.htm
