摘要

We discuss the rates of convergence for weighted sums of rho (au) -mixing random variables. We solve an open problem posed by Sung [S.H. Sung, On the strong convergence for weighted sums of rho (au) -mixing random variables, Stat. Pap., 54:773-781, 2013]. In addition, the two obtained lemmas in this paper improve the corresponding ones of Sung in the above-mentioned paper and [S.H. Sung, On the strong convergence for weighted sums of random variables, Stat. Pap., 52:447-454, 2011].
