Modeling International Student Migrant Tables
This paper demonstrates the use of spatial interaction models for international student migrant tables
using a negative binomial regression in order to account for overdispersion. The Expectation-
Maximization (EM) algorithm is used in fitting these models to account for missing cells, which are a
common occurrence in international population mobility tables. Data for the five largest sending and
receiving nations of international student migrants between 1998 and 2005 are used. The results of
fitting a quasi-independent model, main effects models with multiple covariates and interaction models
are compared with respect to the Akaike Information Criterion in order to establish the most
parsimonious model. By using the EM algorithm to determine parameters in these models provides
imputations for cell values previously unknown.

Abstract

This paper demonstrates the use of spatial interaction models for international student migrant tables
using a negative binomial regression in order to account for overdispersion. The Expectation-
Maximization (EM) algorithm is used in fitting these models to account for missing cells, which are a
common occurrence in international population mobility tables. Data for the five largest sending and
receiving nations of international student migrants between 1998 and 2005 are used. The results of
fitting a quasi-independent model, main effects models with multiple covariates and interaction models
are compared with respect to the Akaike Information Criterion in order to establish the most
parsimonious model. By using the EM algorithm to determine parameters in these models provides
imputations for cell values previously unknown.
