Thanks to Kit Baum a new version of -postrcspline- is 
now available from SSC. To install type: 
-ssc install postrcspline- and to update type either 
-adoupdate, update- or -ssc install postrcspline, replace-. 

-postrcspline- provides post-estimation commands for models 
that use restricted cubic splines as predictors. Restricted 
cubic splines are a way of allowing a variable to have a 
non-linear but smooth effect on the outcome variable. The 
two main post-estimation commands in the -postrcspline- 
package are -adjustrcspline- and -mfxrcspline-. With 
-adjustrcspline- one can draw a graph of the predicted 
outcome adjusted for other explanatory variables. With 
-mfxrcspline one can draw a graph of the effect of the 
spline variable on the outcome variable. The previous 
version only worked with -regress-, while this new version 
will work by default with -regress-, -logit-, -logistic-, 
-probit-, -poisson-, -cloglog-, and -glm-, and gives users 
some tools to make it work with more programs.

Ps. I will give a presentation on this package at the 
German Stata Users' Group meeting on Friday, June 26 in 
Bonn.
