[R] Tobit model with panel data

[phil]

Hi Arne,

thanks a lot for your reply, it was really helpful!

Now, after having managed to apply the censReg to my data, I get the
following error message when I enter the command "summary()":

Error in printCoefmat(coef(x, logSigma = logSigma), digits = digits) : 
  'x' must be coefficient matrix/data frame

What does that mean? Actually, I fear that maybe the number of observations
(total: 52; uncensored: 48) is too small. Is that possible?
