| Subject | st: Lowess smoother matrix |
| Date | Wed, 14 Jul 2010 16:25:14 +0200 |
Dear all, I have the following problem: I would like to compare the fit of a linear regression with that from a Lowess-smooth. Now I have been told that I would need the trace of the "smoother matrix" to get the degrees of freedom. Does anybody know how I could obtain this after the Lowess command? Thank you very much in advance for any suggestions! * * For searches and help try: * http://www.stata.com/help.cgi?search * http://www.stata.com/support/statalist/faq * http://www.ats.ucla.edu/stat/stata/
