st: 'cnreg' command to fit Censored-normal regression model

[Tracy Bai <tracy.bai@flinders.edu.au>]

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?
