| Subject | st: How to test whether coefficient change between two models significant |
| Date | Tue, 7 Jun 2011 10:01:25 +0000 |
Hi. I have two linear regression models A and B: A: attribute = c + explanatory_var1 B: attribute = c + explanatory_var1 + explanatory_var2 Given that I know both explanatory variables are significant, I would like to know a way of testing whether the regression coefficient for explanatory_var1 changes significantly when I add in explanatory_var2. Does anyone know a test for this that I could perform in STATA? Many thanks, Sam. * * 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/
