Juli 2010 13:02 An: statalist@hsphsun2.harvard.edu Betreff: Re: AW: st: AW: mfxrcspline : error message in Stata11 Thank you for your replies ! Below is a copy of the part around the error. I noticed that dumy102 and bin103 had been transformed into o.dumy102 and o.bin103. In the previous version, these variables were dropped automatically from the regression model when there was collinearity, but it is no longer the case in stata11 . "As of Stata 11, variables are no longer dropped because of collinearity. Instead, these variables are omitted and are labeled with the “o.” operator in the column names of the resulting parameter vector.", (http://www.stata.com/support/faqs/lang/post.html). This is the cause of the problem. When I drop the collinear variables before running the model, it works (adding "version 10.1:" before the regression model and/or mfxrcspline does not solve the problem) So I guess I need to find a way of dropping the collinear variables variables before running the models (or use Stata10).

I tried to recreate his problem, but all efforts failed. The "click-to-run" examples in the help file do work as expected.
