Dear All, we (Ott Toomet and I) would like to add functions for maximum likelihood (ML) estimations of generalized tobit models of type 2 and type 5 (*see below) in my R package for microeconomic analysis "micEcon". So far we have called these functions "tobit2( )" and "tobit5( )". Are these classifications well known? How are these functions called in other software packages? Should we keep these names or does anybody have better suggestions? (* T. Amemiya (1984): Tobit models: a survey, Journal of Econometrics, and T. Amemiya (1985):...
