Hello,
I am running a pooled logit model. The data is randomly sampled cross sections from 2004 till 2012. I want to check the heteroskedasticity problem. But there is no heteroskedasticity test available for the logit model. How is it possible to test heteroskedasticity then? The probit model is almost similar as the probit model. Therefore I run the hetprob command where I include all independent variables (categorical and continuous independent variables). The test shows that heteroscedasticity is a problem (the prob of the Likelihood-ratio test of lnsigma2 is 0.0001). In addition, what can I do to solve the heteroskedasticity problem in the logit model? And what is the useful procedure to test heteroskedasticity in a logit model?
Best regards,
Nerissa Fanoembi.
