Alternative procedures and associated tests of significance for non- nested hypotheses (Q789139)

The aims of this paper are: (a) to outline various procedures upon which tests of non-nested econometric hypotheses may be based, as well as their associated tests of significance; (b) to stress that different tests based upon the artificial nesting approach correspond to different treatments of its identification problem; (c) to introduce some 'new' tests and to explain the relations between these and some of those hitherto available; (d) to demonstrate that the tests are consistent; and (e) to give a practical example.
