On the complete convergence of weighted sums for an array of rowwise negatively superadditive dependent random variables


Xinghui Wang, Xiaoqin Li, Shuhe Hu*

 
ABSTRACT:     In this paper, the complete convergence and the complete moment convergence of weighted sums for an array of negatively superadditive dependent random variables are established. The results generalize the Baum-Katz theorem on negatively superadditive dependent random variables. In particular, the Marcinkiewicz-Zygmund type strong law of large numbers of weights sums for sequences of negatively superadditive dependent random variables is obtained.
