Mutual Encompassing and Model Equivalence

M. Lu and Grayham Mizon

Economics Working Papers from European University Institute

Abstract: This paper analyzes the properties of mutual encompassing and its relationship to the KLIC equivalence between statistical models. It is shown that models are KLIC equivalent if and only if they are mutually encompassing and mutually Cox-encompassing. Further, within the exponentional familly encompassing implies Cox-encompassing and so mutual encompassing is necessary and sufficient for KLIC equivalence in this family. In addition, it is shown that mutual encompassing is transitive for models in the exponential family.
