Dear Community, does anybody have an idea on how to estimate a system of three seemingly unrelated regressions, two of which being TOBIT and one OLS?
Background: I am currently estimating a translog cost function and two corresponding cost share equations using systemfit and the seemingly unrelated regression ("SUR") specification. However, I consider it more appropriate to estimate the cost function via OLS and the cost share equations via TOBIT due to some peculiarities of the data (but still as SUR). I am looking forward to your replies!! Warm regards, Tom (I have checked on various help sites but found nothing that could be applied to this specific problem.)
