Tests for the equality of conditional variance functions in nonparametric regression
(Institute of Mathematical Statistics, 2015)
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 distributions ...
