In the paper, the complete convergence for the maximum of weighted sums of negatively superadditive dependent(NSD, in short) random variables is investigated by using the Rosenthal type inequality. Some su?cient conditions are presented to prove the complete convergence. The result obtained in the paper generalizes some corresponding ones for independent random variables and negatively associated random variables. 相似文献

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\v{a}taru\ucite{4}, Liang et al.\ucite{5}, Guo\ucite{6} and Gut\ucite{21} to sequences of negatively orthant dependent random variables, but also improve them. 相似文献

Complete Convergence for Weighted Sums of Negatively Superadditive Dependent Random Variables 下载免费PDF全文
Let $\{X_n,n\geq1\}$ be a sequence of negatively superadditive
dependent (NSD, in short) random variables and $\{a_{nk}, 1\leq
k\leq n, n\geq1\}$ be an array of real numbers. Under some suitable
conditions, we present some results on complete convergence for
weighted sums $\sum_{k=1}^na_{nk}X_k$ of NSD random variables by
using the Rosenthal type inequality. The results obtained in the
paper generalize some corresponding ones for independent random
variables and negatively associated random variables. 相似文献

Complete Convergence of Weighted Sums for Arrays of Rowwise $m$-Negatively Associated Random Variables 下载免费PDF全文
In this paper, we discuss the complete convergence of weighted sums for
arrays of rowwise $m$-negatively associated random variables. By applying moment
inequality and truncation methods, the sufficient conditions of complete convergence
of weighted sums for arrays of rowwise $m$-negatively associated random variables are
established. These results generalize and complement some known conclusions. 相似文献

In this paper, the complete convergence and the complete moment convergence for extended negatively dependent (END, in short) random variables without identical distribution are investigated. Under some suitable conditions, the equivalence between the moment of random variables and the complete convergence is established. In addition, the equivalence between the moment of random variables and the complete moment convergence is also proved. As applications, the Marcinkiewicz-Zygmund-type strong law of large numbers and the Baum-Katz-type result for END random variables are established. The results obtained in this paper extend the corresponding ones for independent random variables and some dependent random variables. 相似文献

In this article, applying the result of complete convergence for negatively associated (NA) random variables which is obtained by Chen et al.\ucite{14}, the equivalent conditions of complete convergence for weighted sums of arrays of row-wise negatively associated random variables is investigated. As a result, the corresponding results of Liang\ucite{11} is generalized, moreover, the proof procedure is simplified greatly which is different from truncation method of Liang's. Thus, Gut's\ucite{13} result on Ces\`{a}ro summation of i.i.d. random variables is extended. 相似文献

Complete Convergence for Randomly Weighted Sums of Random Variables Satisfying Some Moment Inequalities 下载免费PDF全文
For random variables and random weights satisfying Marcinkiewicz-Zygmund and Rosenthal type moment inequalities, we establish complete convergence results for randomly weighted sums of the random variables. Our results generalize those of(Thanh et al. SIAM J. Control Optim., 49,106–124(2011), Han and Xiang J. Ineq. Appl., 2016, 313(2016), Li et al. J. Ineq. Appl., 2017, 182(2017), and Wang et al.

In this article, we study the complete convergence for weighted sums of widely orthant dependent random variables. By using the exponential probability inequality, we establish a complete convergence result for weighted sums of widely orthant dependent ran-dom variables under mild conditions of weights and moments. The result obtained in the paper generalizes the corresponding ones for independent random variables and negatively dependent random variables. 相似文献
