Stability of relaxed calibration
N. T. Longford

Abstract

We find an upper bound for the change of the calibration estimate of the population total of a variable when the auxiliary information is supplemented by another variable with a known population total. This upper bound can be interpreted as a measure of sensitivity of the estimate to unavailable auxiliary information and considered as a factor in deciding whether to pursue further data sources that would be included in calibration.
