Correlated random effects for longitudinal and survival analysis
Professor Robin Henderson
University of Lancaster
This talk will describe the use of a correleted gamma frailty model in
three application areas. The first is modelling spatial
variation in leukaemia survival using data from the North West Regional
Leukaemia Register. The frailty model is used to
investigate whether or not there is variation in survival across the
region, over and above that which can be explained by
measured risk factors. The second application is based on the analysis
of longitudinal count data from a trial on the use of
patient-controlled analgesia. The counts are requests for morphine in
four-hourly intervals and the frailty is used to describe
time-varying subject effects. The final application is also longitudinal
count data, on diarrhoea episodes from a Brazilian
sanitation study, this time complicated by the possibility of
informative dropout.
