Abstract:
We propose a novel class of specification tests for regression models with measurement errors. The highlight of our method is the introduction of a projection device to eliminate the parametric estimation effect, which is a common issue in nonsmoothing type tests. The resulting projection-based tests have asymptotic null distributions that are invariant to the estimator used. Besides, the proposed method allows for a slower convergence rate of the parametric estimator. We suggest a convenient multiplier bootstrap method to simulate the critical values as accurately as desired. Finally, we evaluate the finite sample performance of the proposed tests through Monte Carlo simulations.
