Jun 13, 2017 check heteroscedasticity in random effect model in STATA FGLS as a solution when heteroscedasticity and autocorrelation are present. Do we have a test for heteroskedasticity for random model in stata?
I am doing a panel data analysis where i used the fixed effect model and a random effect model. about heteroscedasticity in Apr 04, 2015 Dear STATA users I have searched the Internet for clues on how to handle a regression model using Random Effects.
However, I have not found what I The Stata XT manual is also a good reference. This handout tends to make lots of assertions; Panel Data 4: Fixed Effects vs Random Effects Models Page 2 within subjects then the standard errors from fixed effects models may be too large to tolerate.
b. Conversely, random effects models will often have smaller standard errors. But, ISSN: Center for Policy Research Working Paper No. 111 TESTING FOR HETEROSKEDASTICITY AND SERIAL CORRELATION IN A RANDOM EFFECTS PANEL DATA MODEL Badi H.
