TL;DR: Simulation results show the EL testing procedure performs well in a variety of scenarios when X and Y are strictly PQD, and a distribution-free test statistic is created that integrates a localized EL ratio test statistic with respect to the empirical joint distribution ofX and Y.
Abstract: We develop an empirical likelihood (EL) approach to test independence of two univariate random variables X and Y versus the alternative that X and Y are strictly positive quadrant dependent (PQD). ...

TL;DR: In this article, a uniformly strongly consistent estimator of a life distribution function is provided and the convergence in distribution of the estimator at a point where H ( x ) ∕ x is increasing using the arg max theorem is derived.
