The generalized estimation equation (GEE) method, one of the generalized linear models for longitudinal data, has been used widely in medical research. However, the related sensitivity analysis problem has not been explored intensively. One of the possible reasons for this was due to the correlated

โฆ Synopsis
Data from a litter matched tumorigenesis experiment arc analysed using a gencralised h e a r mixed model (GLMM) approach to the analysis of clustered survival data in which there is a dependence of failure time observations withii the same litter. Maximum likelihood (ML.) and residual maximum likelihood (REML.) estimates of risk variable parameters, variance component parametem and the prediction of random effects are given. Estimation of treatment effect parameter (Carcinogen effect) has good agreement with previous analyses obtained in the literature though the dependence struchlre withii a litter is modelled in different ways. The variance component estimation provides the estimated dispersion of the random effects. The prediction of random effects. is ustful. for instance, in identifying high risk litters and individuals. The pment analysis illustrates its wider application to detecting increased risk of occurrence of disease in particular families of a study population.
