st: various changes to SSC material
Thanks to Kit Baum, a new package -glmcorr-
and various revised packages are now
available from SSC. Stata 7 is required
for all software.
-glmcorr- calculates a correlation measure of
predictive power for GLMs after -glm-, namely
the correlation (and the jackknifed correlation)
between the response and the fitted or predicted
response, together with the root mean square error.
Zheng and Agresti (Statistics in Medicine 2000)
discuss this correlation as a general measure
of predictive power for GLMs.
This package was first posted on
1 October and described in detail
in a posting on that day. Some extra
functionality has been added. Please
note that the syntax has changed.
This is a fairly general residual vs
fitted plot program. A new -fscale()-
option has been added to allow specified
transformation of fitted values on
