I have a hunch that you will want to manipulate the content of these
matrices further. So note that you cannot directly work with the elements of
the returned matrices. You have to define a new matrix first.

Betreff: st: 'cnreg' command to fit Censored-normal regression model
I am learning how to use 'cnreg' command to fit Censored-normal
regression model, when I tried to get coefficient vector e(b), I got the
error information like below,
. display e(b)
matrix operators that return matrices not allowed in this context
r(509);
Matrices
e(b) coefficient vector
e(V) variance-covariance matrix of the estimators
How to fix the problem here?
