In Cox regression you do not get one single time to event, but a probability
distribution of different times to event, i.e. a survival curve. There is
some probability that the event will occur at time 1, at time 2, and so on.
The survival curve is one standard output. There is a baseline hazard curve
(the hazard curve is the opposite, how many hazards occur per unit of time)
and different hazard curves for subjects affected by different risk factors,
increasing or decreasing the baseline situation.

Subject: Computing time to event from Cox regression results
Dear SPSS list,
Can anyone point me in the right direction for estimating time to event from
Cox PH regression parameter estimates?
Kind regards,
Chris.
