- An Extension to the Scale Mixture of Normals for Bayesian Small-Area Estimation Francisco J. Torres-Avilés Gloria Icaza Reinaldo B. Arellano-Valle Física, Astronomía y Matemáticas Relative risk Incidence rate Disease mapping Markov random Feld Hierarchical model This work considers distributions obtained as scale mixture of normal densities for correlated random variables, in the context of the Markov random ¿eld theory, which is applied in Bayesian spatial intrinsically autoregressive random effct models. Conditions are established in order to guarantee the posterior distribution existence when the random ¿eld is assumed as scale mixture of normal densities. Lung, trachea and bronchi cancer relative risks and childhood diabetes incidence in Chilean municipal districts are estimated to illustrate the proposed methods. Results are presented using appropriate thematic maps. Inference over unknown parameters is discussed and some extensions are proposed. 2012 artículo científico 0120-1751 https://www.redalyc.org/articulo.oa?id=89923144001 en http://www.redalyc.org/revista.oa?id=899 Revista Colombiana de Estadística application/pdf Universidad Nacional de Colombia Revista Colombiana de Estadística (Colombia) Num.2 Vol.35
