It depends on several factors. You need answers to all these questions: How
many events occurred, ... and was the period of observation long enough to
cover a significant fraction of the life expectancy, …. and is there external
evidence or theory that will help establish that this process shou

I read this list a day late as a digest so my answers are rarely the first. (Which is
nice as David W answers most of the survival questions for me!)
What you are asking is reasonable, and in fact is common practice in the realm of
industrial reliability, e.g., Meeker and Escobar, Statistical
Thank you David for your answer.
Some follow-up questions:
- So, do you think that try to estimate the life expectancy would be risky
and probably not justifiable? Is there some sort of 'confidence' that the
model could give me for a prediction?

David:
I may have misunderstood you here, specifically:
"As such I would ask if you really wanted to use a parametric survival
model in the first place? "
The K-M curve is , of course, a **non-parametric** fit, and that is
why there can be no mean survival time unless the last point is a
death.

Are you sure you want to use life expectancy as the outcome? In order
Dear All,
I would like to build a model, based on survival analysis on some data, that
is able to predict the /*expected time until death*/ for a new data
instance.
Data
For each individual in the population I have the, for each unit of time, the
status information and several continuous covariat
