Dear all, 
Following a parametric survival regression, 
I can use -predict- with the -surv- option to get 
the survival function; but I only do not seem to have 
any choice over when it is calculated for.

The help file promises me values for S(t|t_0), 
and I would like to set both t and t_0 myself.
But they seem to be set automatically, 
at the time of entry and exit of the subject.

Is there a simple way of doing this?
If not, is there any chance of it being included 
in a future version of Stata?

Many thanks.
