Integrated Conditional Moment Tests for Parametric Conditional Distributions
نویسندگان
چکیده
This paper extends the Integrated Conditional Moment (ICM) test for the functional form of nonlinear regression models to tests for parametric conditional distributions. This test is formed on the basis of the integrated squared difference between the empirical characteristic function of the actual data and the characteristic function implied by the model. This test is consistent, and has nontrivial power against √ n -local alternatives. To avoid numerical evaluation of the conditional characteristic function of the model distribution, a simulated integrated conditional moment (SICM) test is proposed, where each theoretical conditional characteristic function is replaced by a simulated counterpart, based on a single random drawing from the corresponding conditional distribution. All the properties of the exact ICM test carry over to the SICM test. ∗A previous version of this paper was presented by Herman Bierens at the ”Symposium on Nonparametric Testing in Econometrics”, March 21, 2008, Indiana University.

متن کاملTesting for Nonnested Conditional Moment Restrictions via Conditional Empirical Likelihood
We propose non-nested tests for competing conditional moment resctriction models using a method of empirical likelihood. Our tests are based on the method of conditional empirical likelihood developed by Kitamura, Tripathi and Ahn (2004) and Zhang and Gijbels (2003). By using the conditional implied probabilities, we develop three non-nested tests: the moment encompassing, Cox-type, and effcien...

We propose non-nested hypotheses tests for conditional moment restriction models based on the method of generalized empirical likelihood (GEL). By utilizing the implied GEL probabilities from a sequence of unconditional moment restrictions that contains equivalent information of the conditional moment restrictions, we construct Kolmogorov-Smirnov and Cramér-von Mises type moment encompassing te...
