Subject   st: update postrcspline available from SSC

Bruno Schoumaker reported that -mfxrcspline- stopped with an error if
the previous estimation command automatically dropped one or more
variables in Stata 11. This problem also affected -adjustrcspline-.
It has been solved for both programs and the updated package is,thanks
to Kit Baum, now available on SSC. To install it type in Stata
-ssc install postrcspline- or -adoupdate, update-.

The -postrcspline- package consists of two progams, -adjustrcspline- 
and -mfxrcspline-, which help with the interpretation of explanatory/
independent/x variables that have been added to the model as 
restricted cubic splines. -adjustrcspline- displays a graph of the 
predicted outcome against the spline variable while keeping all other 
explanatory/independent/x variables constant. -mfxrcspline- displays a
graph of the marginal effect of the spline variable against the spline
variable. Examples of these graphs can be seen at:
