Estimation and Interpretation of a Nonlinear Migration Model

Abstract

s data are for only one period, then the subscript t can be dro ped. However, in order to have enough degrees of freedom for the statistical inference about the Beterminants of the departure robabilities, the number of origins will then have to be large. If the data are stratified in terms ofrelevant attributes such as age and labor force status, then equation (1) can be applied to each relatively homogeneous subpopulation.
