Dear friends,
My data is a kind of cesored data. Some of them are left-censored,
right-censored, and others interval like the below.

I want to know mean/median value and standard error by fitting the
parameters to Weibull model. When I tried <stset>, <streg> or <weibull>
in the commands of survival-time analysis, STATA didn't identify the
left-censored and right-censored data. If there is no way to handle
left-censored data, I can replace <.> in the left with the number of
0.1. Still there was some problem with right-censored data. STATA
analyzed only interval data. I can't go agead further. Is there someone
who has analyzed censored data?
Please, help me, I really appreciate it.
