Abstract

In this paper, we establish a general result on complete moment convergence and the Marcinkiewicz–Zygmund-type strong law of large numbers for weighted sums of m-asymptotic negatively associated random variables, which improve and extend some existing ones. As applications of our main results, we present a result on complete consistency for the weighted estimator in a nonparametric regression model and a result on strong consistency for conditional Value-at-risk estimator based on m-asymptotic negatively associated errors. We also carry out some numerical simulations to confirm the theoretical results.
