摘要
利用Rosenthal不等式,讨论条件为■,■的次线性期望下m-END(m-extended negatively dependent)随机变量序列加权和的几乎处处收敛性.将经典概率空间中END序列加权和的几乎处处收敛性推广到次线性期望下m-END随机变量序列加权和的几乎处处收敛性.
By using Rosenthal’s inequality,we discussed almost sure convergence of weighted sums for m-END(m-extended negatively dependent)random variable sequence with the condition of ■,■ under sub-linear expectations.Almost sure convergence of weighted sums for END sequence in the classical probability space was extended to the almost sure convergence of weighted sums for m-END random variable sequence under the sub-linear expectations.
