A note on intrinsic conditional autoregressive models for disconnected graphs

Publication date: August 2018Source: Spatial and Spatio-temporal Epidemiology, Volume 26Author(s): Anna Freni-Sterrantino, Massimo Ventrucci, Håvard RueAbstractIn this note we discuss (Gaussian) intrinsic conditional autoregressive (CAR) models for disconnected graphs, with the aim of providing practical guidelines for how these models should be defined, scaled and implemented. We show how these suggestions can be implemented in two examples, on disease mapping.
