Tests for the equality of conditional variance functions in nonparametric regression
(Institute of Mathematical Statistics, 2015-08-27)
In this paper we are interested in checking whether the conditional variances are equal in k ≥ 2 location-scale regression models. Our procedure is fully nonparametric and is based on the comparison of the error ...

Computationally efficient goodness-of-fit tests for the error distribution in nonparametric regression
(Instituto Nacional de Estatística (Portugal), 2018-01)
Several procedures have been proposed for testing goodness-of-fit to the error distribution in nonparametric regression models. The null distribution of the associated test statistics is usually approximated by means of a ...

A non-parametric ANOVA-type test for regression curves based on characteristic functions
(Wiley, 2015-03)
This article studies a new procedure to test for the equality of k regression curves in a fully nonparametric context. The test is based on the comparison of empirical estimators of the characteristic functions of the ...
