Valeriano,
The Breusch-Pagan statistic test the null that var(vit)=0, so under the null
OLS is consistent. If you accept the null, that means that you cannot
estimate the model using Random Effects. I recommend you to estimate with
Fixed Effects estimator and perform an F-test in order to evaluate the joint
significance of the specific effects (at the bottom of the regression table
appears this statistic). If you accept the null, you can conclude the
absence of specific effects, so you can use OLS.
I hope this will help you
Mariano

Subject: st: Breusch-Pagan test and random effects estimation
Hello all,
I have other beginer�s question. When you run a random effects estimation on
panel data, and you compute the Breusch-Pagan test for random effects.
If the statistic acept the null hypothesis, Can we conclude that the random
effects estimator is better than the fixed effects one?
Thank you very much.
