| Subject | st: Testung for multicollinearity after FD |
| Date | Sun, 20 May 2012 13:17:22 +0200 |
Dear statalists, I am using Stata 11.2 and I am working on two period panel data. My prefered method is first differencing. Eventhough I have been reading many previous statalist threads on this topic, I still don't know whether I should test for multicoll. before or after first-differencing. How would I test for mullticol. after FD? Is the -vif- command reliable after FD?
