This article reviews and discusses the problem of choosing smoothing parameters and resampling schemes for specification tests in econometrics. While smoothing is used for the regularization of the non-specified parts of the null hypothesis and omnibus alternatives, the resampling serves for...

The study analyzes the performance of the Zheng test for functional form in different scenarios concerning the distribution approximation of the test statistic. We apply the test statistic for validating simple wage functions.
