This is my first time posting, so please bear with me...
Can someone point me to a SAS proc or macro for the
nonparametric analysis of survival/failure-time/life-time
data with both left- and right-censored observations? The
3 procs that I found for handling censored data are: PHREG,
LIFETEST, and LIFEREG. The first two do not seem (at least
to me at first glance) to allow for left-censored (or
interval-censored) data. The third proc does, but relies
on parametric distributions.
Is there another proc that will do what I want?
Is there a macro that I can grab off the net?
Can either PHREG or LIFETEST be "tricked" into handling
Thanks in advance for any help that anyone can give to me.
I appreciate it. Bye,
