Non-parametric Specification Testing of Non-nested Econometric Models.*

چکیده
We consider the non-nested testing prqblem of non-parametric regressions. We show that, when the regression functions are unknown under both the null and the alternative hypotheses, an extension of the J-test procedure of Davidson and Mackinnon (1981) will lead to a test statistic with well defined asymptotic properties. The derivation of the test statistic involves double kernel estimation. Monte Carlo simulations suggest that the test has good size and power characteristics.

Testing Separate Dynamic Nonlinear Econometric Models
A very general test statistic for contrasting two nested or nonnested dynamic nonlinear econometric models is presented. It is based on the idea of testing the specification of the first model by using the second model to generate moment conditions for the efficient method of moments (EMM) estimation procedure. The testing procedure also provides guidance as to what aspects of the model should ...
متن کاملA Simple Parametric Model Selection Test
We propose a simple model selection test for choosing among two parametric likelihoods which can be applied in the most general setting without any assumptions on the relation between the candidate models and the true distribution. That is, both, one or neither is allowed to be correctly specified or misspecified, they may be nested, non-nested, strictly non-nested or overlapping. Unlike in pre...
متن کاملLarge Sample Sieve Estimation of Semi-Nonparametric Models∗
Often researchers find parametric models restrictive and sensitive to deviations from the parametric specifications; semi-nonparametric models are more flexible and robust, but lead to other complications such as introducing infinite dimensional parameter spaces that may not be compact. The method of sieves provides one way to tackle such complexities by optimizing an empirical criterion functi...
متن کاملTesting non-nested models for non-negative data with many zeros∗
In economic applications it is often the case that the variate of interest is nonnegative and its distribution has a mass-point at zero. Many regression strategies have been proposed to deal with data of this type but, although there has been a long debate in the literature on the appropriateness of different models, formal statistical tests to choose between the competing specifications are no...
متن کاملTerm Structure of Risk under Alternative Econometric Specifications
This paper characterizes the term structure of risk measures such as Value at Risk (VaR) and expected shortfall under different econometric approaches including multivariate regime switching, GARCH-in-mean models with student-t errors, two-component GARCH models and a non-parametric bootstrap. We show how to derive the risk measures for each of these models and document large variations in term...
