migest-package: 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 categorised by a further set of characteristics, such as ethnicity, employment or health status (cm3, ipf3 and ipf3.qi). All these routines are based on indirect estimation methods where marginal totals are known, and a Poisson regression (log-linear) model is assumed.

The flow from stock function, ffs acts as a wrapper for a combination of some of these estimation routines with further adjustments for changes in foreign born stocks over a period. The demo files, demo(cfplot_reg) and demo(cfplot_nat), produce circular migration flow plots for migration estimates from Abel and Sander (2014), which were derived using the ffs function.
