Greetings Statalisters - 
I'm using STATA v8 and when I use the 'predict' command for the 
median and the standard error of the Weibull distribution the 
same value is returned.  The code that precedes the 'predict' 
command is pasted below:
	stset time
	streg, dist(weibull)
	nlcom (theta:exp([ln_p]_b[_cons])) (beta:exp(-b[_cons]))

For predict, I used the following code:
	predict med
	predict stdp

Any suggestions or am I missing something obvious?

kindest regards, 
Clint
