In this paper, the complete moment convergence and the integrability of the
supremum for weighted sums of negatively orthant dependent (NOD, in short)
random variables are presented. As applications, the complete convergence and
the Marcinkiewicz-Zygmund type strong law of large numbers for NODrandom
variables are obtained. The results established in the paper generalize some
corresponding ones for independent random variables and negatively associated
random variables.
Keywords: negatively orthant dependent random variables, complete convergence, complete moment convergence, weighted sums
