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
Appreciate your help.
