该文把同分布的两两NQD列的Kolmogorov强大数定律推广到了在一类广泛的条件下的不同分布的情形, 为此而建立的Kolmogorov Chung型强大数定律本身也是有意义的.

本文对一类相当广泛条件下的不同分布两两NQD列的部分和及乘积和强大数定律进行讨论,在更弱的条件下,推广了已有的几个最新结果,使之成为本文结论的推论,所得结论更具优越性,这些结论都是独立情形经典结果的推广. 相似文献

本文首先给出两两 NQD列的 Kolmogorov型不等式,进而讨论两两 NQD列的收敛性质,获得了与独立情形一样的Baum和Katz完全收敛定理,几乎达到独立惰形著名的Marcinkiewicz强大数定律、三级数定理等结果. 相似文献

By using the moment inequality, maximal inequality and the truncated method of random variables, we establish the strong law of large numbers of partial sums for pairwise NQD sequences, which extends the corresponding result of pairwise NQD random variables. 相似文献

Strong convergence of pairwise NQD random sequences 总被引:1,自引:0,他引:1
Strong limit theory is one of the most important problems in probability theory. Some results on the convergence of pairwise NQD random sequences have been presented. This paper further analyzes the strong convergence of pairwise NQD sequences and generalizes partial results of Wu [Q.Y. Wu, Convergence properties of pairwise NQD random sequences, Acta Math. Sinica 45 (3) (2002) 617-624 (in Chinese)]. Since no general moment inequalities are given as so far, we avoid this problem and obtain a class of strong limit theorem for NQD sequences and some corresponding conclusions by use of truncation methods and generalized three series theorem, which are the supplements to the previous fruits. 相似文献

It is known that the dependence structure of pairwise negative quadrant dependent (NQD) random variables is weaker than those of negatively associated random variables and negatively orthant dependent random variables. In this article, we investigate the moving average process which is based on the pairwise NQD random variables. The complete moment convergence and the integrability of the supremum are presented for this moving average process. The results imply complete convergence and the Marcinkiewicz–Zygmund-type strong law of large numbers for pairwise NQD sequences. 相似文献

In this paper, the authors study the strong law of large numbers for partial sums of pairwise negatively quadrant dependent (NQD) random variables. The results obtained improve the corresponding theorems of Hu et al. (2013), and Qiu and Yang (2006) under some weaker conditions. 相似文献
