e(b) and e(V) are matrices and so not valid substrate for-display-.

Try:

matrix list e(b)
matrix list e(V)

Subject: 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?

Tracy
