Methods for the Indirect Estimation of Bilateral Migration

Description

The migest package contains a collection of R functions for indirect methods to estimate bilateral migration flows in the presence of partial or missing data. Methods might be relevant to other categorical data situations on non-migration data, where for example, marginal totals are known and only auxiliary bilateral data is available.

The estimation methods in this package can be grouped as 1) functions for origin-destination matrices (cm2 and ipf2) and 2) functions for origin-destination matrices categorized by a further set of characteristics, such as ethnicity, employment or health status (cm3, ipf3 and ipf3_qi). Each of these routines are based on indirect estimation methods where marginal totals are known, and a Poisson regression (log-linear) model is assumed.

The ffs_diff, ffs_rates and ffs_demo functions provide different methods to estimate migration bilateral flows from changes in stocks, see Abel and Cohen (2019) for a review of different methods. The demo files, demo(cfplot_reg2), demo(cfplot_reg) and demo(cfplot_nat), produce circular migration flow plots for migration estimates from Abel(2018) and Abel and Sander (2014), which were derived using the ffs_demo function.
