Assessing the migration potential and predicting future migration streams are among the most relevant, yet least well understood topics of migration research. The usual approach taken to address aggregate-level prediction problems is to fit ad hoc specifications to historical data, and to...

We consider fixed scan Gibbs and block Gibbs samplers for a Bayesian hierarchical random effects model with proper conjugate priors. A drift condition given in Meyn and Tweedie (1993, Chapter 15) is used to show that these Markov chains are geometrically ergodic. Showing that a Gibbs sampler is...

Un número creciente de aplicaciones utilizan escenarios en los que, para inferir efectos heterogéneos, un investigador compara distintas unidades. Ejemplos de diseños de investigación son aquellos que incluyen a niños que se mudan de barrio, trabajadores que cambian de empresa, pacientes...
