Equivalent Conditions of Complete Convergence for Weighted Sums of Sequences of Negatively Dependent Random Variables

الملخص EN

The complete convergence for weighted sums of sequences of negatively dependent random variables is investigated.

By applying moment inequality and truncation methods, the equivalent conditions of complete convergence for weighted sums of sequences of negatively dependent random variables are established.

These results not only extend the corresponding results obtained by Li et al.

(1995), Gut (1993), and Liang (2000) to sequences of negatively dependent random variables, but also improve them.
