Several Tests for Model Specification in the Presence of Alternative Hypotheses

  • Computer Science


Several procedures are proposed for testing the specification of an econometric model when one or more models purport to explain the same phenomenon. These procedures are closely related, although not identical, to non-nested hypothesis tests proposed by Pesaran and Deaton, and have similar asymptotic properties. They are simple conceptually and computationally, and unlike earlier techniques, may be used to test against several alternative models simultaneously. Some empirical results suggest that ability of the tests to reject false hypotheses is likely to be good in practice.
