Hi Kathy,

Expected refers to the expected number of events for an individual over the
observed at-risk interval.  Most of the theory behind Therneau's 'survival'
package explanation of many of its functionality is covered in the following


and of course in his book "Modeling Survival Data".

Subject: [R] predict.coxph

Hi everyone, 

Can anyone give me more details about the 'lp', 'risk', 'terms', and
options from the predict.coxph function?
I actually found that risk is obtained from exp(lp). I can't find
information on 'expected' type however. Is anybody can expand the
information on this function?

Thank you in advance, I will appreciate it.
