Disease mapping studies have been widely performed with considering only one disease in the estimated models. Simultaneous modeling of related diseases can also be a valuable tool both from the epidemiological and from the statistical point of view. In particular, when we have several measurements recorded at each spatial location, we need to consider multivariate models in order to handle the dependence among the multivariate components as well as the spatial dependence between locations. These models can be studied in the class of spatial generalized linear mixed models (SGLMMs). In this talk, we study these spatial mixed models and conduct a frequentist analysis of SGLMMs with multivariate conditional autoregressive (CAR) models for areal data. The performance of the proposed approach is evaluated through simulation studies and also by a real dataset.
