* Pseudo R 2 is a measure of goodness of fit similar to R 2 in ordinary least squares. The residuals are calculated based on the maximum likelihood estimators. For details of its calculation see the EasyReg manual, available at http://econ.la.psu.edu/~hbierens/EasyRegTours/TOBIT_Tourfiles/TOBIT.PDF.
