I am attempting to do a parametric survival analysis with interval censored
data. However, I don't know if Stata can handle interval censoring. Does
anyone know how to do this using Stata? (I am working with release 9)
Alternatively, if it is not possible (or easy), two alternatives are:
1. find the midpoint of each interval and use that
2. assuming that each item of data is interval censored between time T1 and
some later time T2, duplicate each item so that the same item appears both
as a positive outcome at time T2 and as a right censored outcome at T1.
If anyone has any views on the accuracy and applicability of either of
these methods I'd be grateful to hear them.
Thanks
John
