Survey calibration weights typically minimize the distance from indetermined weights to a set of pre-speciﬁed design weights, subject to moment conditions. For missing data applications, there is no known design weights, and calibration usually requires estimating inverse probability weights, see Chan and Yam (2014) for a recent review.
