title: Migration models incorporating interdependence of movers.
abstract: "In this paper we describe a development of the Poisson model in which households are assumed to migrate independently, but the expected number of migrants is given by a Poisson distribution generalized by an empirically given household-size distribution.... The model is fitted to data on short-distance migration within the English county of Hereford and Worcester.... The data set used comes from the Special Migration Statistics (series II) produced as part of the 1981 British Census."  The sparse nature of the data raises problems in assessing goodness of fit, because the deviance value is unusually low. This is tackled using simulation methodology.
