Thanks to Kit Baum an update of the -margdistfit- package is now
available from SSC.

-margdistfit- is a post-estimation command for checking how well
distributional assumptions of a parametric regression model fit to the
data. It does so by comparing the marginal distribution implied by the
regression model to the distribution of the dependent variable. This
comparison is done through either a probability-probability plot, a
quantile-quantile plot, a hanging rootogram, or a plot of the two
cumulative density functions. Examples can be found here:

This new version adds support for -poisson-, -zip-, -nbreg-, and
-zinb-, in addition to support for -regress- and -betafit- (available
from SSC) that was already implemented.

Hope that some of you will find this useful,
