OLS regression with heteroscedasticy problem
by 3J LEMA
For my panel data (all continuous variables; 1 DV, 4 IVs; 8 time points for
each of the 5 companies), the Breusch-Pagan test is nonsignificant
(Chi-square(4) = 1.77291, p= 0.777434) implying that both Random effects
model and fixed effect model are not appropriate. I used the OLS
regression with heteroscedasticy problem. Any suggestions on how to remedy
this?
Appreciate your help.

Unprofessional people in this mailing list
by 3J LEMA
People in this group are mostly too arrogant, egoistic, unprofessional,
etc. These people feel that they are brilliant, wise, intelligent, smart,
and knowledgeable. I doubt if they are really knowledgeable in
the field. Don't ask me why; you can identify them by reading their
comments. Why give comments when your words are not helpful to
other people?
