Thanks to the egregious Kit Baum, various
packages have been added to or revised on SSC:

-qpfit-
=======

This is a bundle of programs to produce
QQ and PP plots for data versus various
fitted distributions: Dagum, Singh-Maddala,
lognormal, generalised beta (second kind)
(some of these have other names too).

The package is a supporting act to the Stephen
Jenkins Quartet announced last Sunday:

Date: Sun, 18 Mar 2007 23:06:05 -0000 (GMT)


Some additional programs for fitting distributions by maximum likelihood are now available to download from SSC (with thanks, as ever, to Kit Baum).

The distributions that can be fitted are:

Generalized Beta of the Second Kind (4 parameter): module -gb2fit-
Dagum (3 parameter): module -dagumfit-
Singh-Maddala (3 parameter): module -smfit-
Lognormal (2 parameter): module -lognfit-
-----------------------------------------------------

Stata 8 is required.

Note that other packages provide similar support
for several other distributions.

-triplot-
=========

This is for triangular plots. Stata 8 is required.

Scott Merryman found a bug and explained the fix.

-parplot-
=========

This is for parallel coordinates plots. Stata 8 is required.

Scott Merryman found a bug and explained the fix.
I added some extra references to the help.

Thanks to Scott for his exemplary bug reports.
