Summary

Generalised ratio adjustment is a method to reconcile conflicting information as described in the module “Micro-Fusion – Reconciling Conflicting Microdata”. The method uses multiplicative adjustments, just as the methods prorating (see the module “Micro-Fusion – Prorating”) and the KL adjustments (see the module “Micro-Fusion – Minimum Adjustment Methods”). The generalised ratio adjustments method aims to make the adjustments as uniform as possible. Furthermore, and in contrast with the other adjustment methods, the method can result in adjustments to variables that are not involved in any of the constraints.
