Well done Maarten!
This is a very useful program especially in multiple regression. When
used with pwcorr one can decide if certain variables add any
additional information to the model by comparing the correlation and
partial correlation coefficient.

Thanks to Kit Baum a new package is available on ssc: -pcorrmat-. It
displays a matrix of partial correlations that are controlled for a
fixed set of covariates. Use -ssc describe- for more information and
-ssc install- to install.
It is an extension of a program I posted on November 26th on statalist
(http://www.stata.com/statalist/archive/2006-11/msg00747.html)
Raphael Fraser commented later that it would be "a perfect program" if
it included p-values
(http://www.stata.com/statalist/archive/2006-11/msg00752.html). Always
having wanted to write a perfect program, I added those p-values and
submitted it to ssc.
