Full-text available. May We show that some nonparametric specification tests can be robust to disturbance autocorrelation. This robustness can be affected by the specification of the true model and by the sample size. Once applied to the prediction of changes in the Euro Repo rate by means of an index based on ECB wording, we find that the least sensitive nonparametric tests can have a comparable performance to linda RESET test with robust standard errors.
Show more. Li Suojin Wang. A simple consistent test is considered and a bootstrap method is proposed for testing a parametric regression functional form. It is shown that the bootstrap method gives a more accurate approximation to the null distribution of the test than the asymptotic normal theory result.
We also propose a elisson test for testing a parametric partially linear model versus a semiparametric partially linear alternative. On the performance of nonparametric specification tests in regression models. Some recently developed nonparametric specification tests for regression models are described in a unified way.
The common characteristic of these tests is that they are consistent against any alternative hypothesis.

The performance of the test statistics is compared by means of Monte Carlo simulations, analysing how heteroskedasticity, number of regressors and bandwidth selection influence the results. The statistics which do not use a bandwidth perform slightly better if the regression model has only one regressor; otherwise, some of the statistics which use a bandwidth behave better if the bandwidth is chosen adequately.
These statistics are applied to test the specification of three commonly used Mincer-type wage equations with Uruguayan and Spanish data; all of them are rejected. On the finite sampling properties of the Zheng test for omitted and irrelevant variable problems. The paper conducts simple Monte Carlo simulation investigations to ascertain the finite sample properties of the Zheng test when applied to familiar specification errors in the linda of omitted and irrelevant variable problems.
