Testing increasing dispersion

Abstract

Increasing dispersion in regression analysis means that with positive changes of the explanatory variable the residual variance increases. Motivated by theoretical questions in stability of demand systems we consider the question of increasing dispersion in a nonparameteric way. It amounts to testing the positive definiteness of differences of covariance matrices. The asymptotic distribution of the smallest eigenvalue of this difference is rather complicated that is why we also apply bootstrapping. The proposed method is applied to family expenditure data from the United Kingdom.
