Dear Allstat's members,
Hougaard wrote in a paper the following:
The idea of frailty models for survival data is to consider the variability in life times (or, more generally, time to some specific event) as coming from two separate sources. one source is, of course, simple randomness, and described by hazard function. the other source is described by a random effect (the so called frailty), which is a random variable that is either an individual variable , or a variable common to several individuals....
I remark that the frailty notion is often used in medical applications.
I want to Know if there are others fields which introduce this notion.
I have seen that Dr Alan Kimber (University of Surrey)
have presented "FRAILTY METHODS IN NON-MEDICAL APPLICATIONS" in The General Applications Section of the Royal Statistical Society.
Could some one send me, please, this paper and some references related to frailty methods in non-medical studies.
P.S. I have asked the some question to Dr Kimber but I don't receive any response yet.
Thank you very much
