Incoherence correction strategies in statistical matching

Abstract

We deal with the statistical matching problem and in particular we study the problem related to the managing of inconsistencies. In fact, when logical relations among the variables are present incoherence can arise in the probability evaluations. The aim of this paper is to remove such incoherences by using different methods. Specific precise distances minimization or least committal imprecise probability extensions are adopted. We compare these methods using an exemplifying practical example that brings to light the peculiarities of the statistical matching problem.

Keywords

Statistical matching, incoherence, inference, specialized discrepancy measure.
