Abstract

For an array of dependent random variables satisfying a new notion of uniform integrability, weak laws of large numbers are obtained. Our results extend and sharpen the known results in the literature.

Keywords: uniform integrability, weak law of large numbers, $r$-mean convergence, convergence in probability, martingale difference sequence, negative association, negative dependence
