Hi all,

I tried to check the following and have a feeling what to expect, I
still ask for your quick expert advice, which will be greatly
appreciated:

I am running an experiment where a subject becomes "at risk" once she
reads our invitation, but we only know when we sent her invitation and
the time she agreed to do what we asked (which clearly does not happen
upon receipt immediately). Is there anything I can do in this case for
Stata to be "robust" to this uncertainty?

I checked left censoring and truncation in the manuals, and I am also
uncertain how any method could deal with this kind of uncertainty in
the event time (also, uncensored "enter" time precedes censored
"origin"). Yet you might know something I missed, and I'm happy to
learn the prudent way to set things up (-stset-) in this case.

Thank you!

Laszlo
