[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?
