migest-package: Useful R code for the Estimation of Migration
Description
The migest package contains a collection of R functions that are useful to estimate migration when there is missing data. Included is the ffs routine to estimate migration flows from stock data, as well as various other functions to indirectly estimate flows where marginal totals are known. Functions are illustrated with dummy data.Details

The routines in this package include methods to estimate missing migration data when marginal totals are known. These can be grouped into functions for origin-destination matrices (cm2 and ipf2) and functions for more than two dimensions (cm3, ipf3 and ipf3.qi). All these routines are based on indirect estimation methods where marginal totals are known, under a Poisson regression (log-linear) model assumption.References
