 Comparison between SAS `PROC LIFEREG` and R functions `censReg::censReg` and `survival::survreg` show identical results for the dataset tried. 
 
+Historically and typically the Tobit model is based on the assumption of normal distributed data. Within SAS `PROC LIFEREG` and R `survival::survreg` multiple other different distributional assumption are possible. These include *weibull*, *exponential*, *gaussian*, *logistic*, *lognormal* and *loglogistic* for `survival::survreg`. These include *EXPONENTIAL*, *GAMMA*, *LLOGISTIC*, *LOGISTIC*, *LOGNORMAL*, *NORMAL*, *WEIBULL* for `PROC LIFEREG`.
