Dear All
There will be another seminar on Friday, February 16th,
at 14:00, in Room A2002. This is at short notice given
the re-arrangement of Professor Jupp's seminar on
Quantum Information. We are very pleased to announce
this seminar.
On Positive Stable Frailty
Dr. Milica Balgojevic.
Keele University, England, UK
February 16th (Friday), 14:00, Room A2002.
Abstract
The most common finite variance frailty distributions used in literature
are the gamma and log-normal. However, within the PH framework, there is a
problem with using these frailty specifications because they do not allow
the PH model to hold unconditionally. It has previously been showed that
the use of infinite variance positive stable frailty distribution resolves
this problem as well as allowing for a higher degree of heterogeneity
among individuals than would be possible using finite-variance frailty
distributions. Various authors have considered positive stable frailty
distribution however always under the assumption that the basic hazard is
of a PH nature. We place focus on the development of a novel frailty model
based on the non-PH CTDL hazard. Developments are made in the Bayesian
framework for the shared frailty scenario.
Tea at 1:45
All welcome!
