Subject | st: apply predict to a different dataset |
Date | Thu, 16 Aug 2012 17:17:48 -0400 |
Hi. This may be a routing matter, but I am attempting this for the first time. I use Stata 10. I have two datasets with some of the same variables.I want to -regress- on the first dataset, then apply the coefficients to run -predict- on the second dataset.
I am thinking that the thing to do is... use set1 regress v1 v2 v3 v4 _return hold somename use set2 _return restore somename, hold predict newvar ---- Is this the right approach?I also wonder whether the -_return- operations are necessary. I note that when I -use- a dataset, the coefficients from the earlier -regress- are still around. But I also wonder if the regress coefficients can be stored in a file that I can reload at a later time -- and then I could proceed to do a -predict-. Note that my actual task is to apply the -predict- to a multitude of additional datasets.
Thanks if anyone can help with this. --David * * 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/
