[Gretl-users] heteroscedastistic tobit model
According to the gretl test for normality of residuals in my estimated Tobit model,
heteroscedasticity is a problem, meaning the Tobit estimator is inconsistent. Does gretl
have an alternative estimator for censored regressions such as a least absolute deviations
estimator or an maximum likelihood estimator that is consistent in the face of non normal
errors?
