Abstract
In this paper, the complete qth moment convergence for weighted sums of sequences of negatively orthant dependent random variables is investigated. By applying moment inequality and truncation methods, the equivalent conditions of complete qth moment convergence for weighted sums of sequences of negatively orthant dependent random variables are established. These results not only extend the corresponding results obtained by Li and Sp\vataru\ucite4, Liang et al.\ucite5, Guo\ucite6 and Gut\ucite21 to sequences of negatively orthant dependent random variables, but also improve them.
