Abstract

In this paper we describe 10 expressions of score and weighted tests, in such a way that the numerators and the denominators are completely specified, including always the possibility of tied observations. We establish the equivalence between score and weighted tests in the general setting of ties. Based upon this equivalence we enunciate two new tests, which complete the jigsaw of the classification of these non-parametric tests in Survival Analysis.
