Publication date: Available online 21 June 2018Source: Spatial and Spatio-temporal EpidemiologyAuthor(s): Georgiana Onicescu, Andrew B Lawson, Jiajia Zhang, Mulugeta Gebregziabher, Kristin Wallace, Jan M. EberthAbstractIn this paper, the spatially explicit survival model is extended by allowing the relation with the explanatory covariates to be spatially adaptive using a threshold conditional autoregressive (CAR) model, further extended to allow the inclusion of multiple threshold levels. The model is applied to prostate cancer survival based on Louisiana SEER registry, which holds individual records linked to vital outcomes and is geocoded at the parish level.
