Hi everyone, Can anyone give me more details about the 'lp', 'risk', 'terms', and 'expected' 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.

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 report: http://cancercenter.mayo.edu/mayo/research/biostat/upload/survival.pdf and of course in his book "Modeling Survival Data".
