Sorry for simple question. Is it correct to say that a CAR model is a spatial lag model and a SAR model is a error spatial model.?
No, it is not. The spatial lag and spatial error models are both SAR - simultaneous autoregressive, while CAR is conditional autoregressive and is not directly comparable. See books by Ripley (1981) or Haining (2003). Roger
I revised some literature where these concepts are not changed. Ivan [[alternative HTML version deleted]]
