该文给出了一些负相协随机变量的指数不等式.这些不等式改进了由Jabbari和Azarnoosh[4]及Oliveira[7] 所得到的相应的结果.利用这些不等式对协方差系数为几何下降情形, 获得了强大数律的收敛速度为n-1/2(log log n)1/2(log n)2.这个收敛速度接近独立随机变量的重对数律的收敛速度, 而Jabbari和Azarnoosh[4]在上述情形下得到的收敛速度仅仅为n-1/3(log n)5/3. 相似文献

对相协随机变量部分和建立一些指数不等式, 这些不等式改进了Ioannides和Roussas (1999)及Oliveira (2005) 所获得的相应结论.利用这些不等式给出一些强大数律, 对协方差系数为几何递减情形,获得了强大数律的收敛速度为n-1/2(log log n)1/2(log n).这个收敛速度接近独立随机变量的重对数律的速度, 而且较好地改进Ioannides 和 Roussas及Oliveira分别获得的速度n-1/3}(log n)2/3和n-1/3(log n)5/3. 相似文献

Strong laws of large numbers play key role in nonadditive probability theory. Recently, there are many research papers about strong laws of large numbers for independently and identically distributed (or negatively dependent) random variables in the framework of nonadditive probabilities (or nonlinear expectations). This paper introduces a concept of weakly negatively dependent random variables and investigates the properties of such kind of random variables under aframework of nonadditive probabilities and sublinear expectations. A strong law of large numbers is also proved for weakly negatively dependent random variables under a kind of sublinear expectation as an application 相似文献

In this paper, we establish strong laws for weighted sums of identically distributed negatively associated random variables.
Marcinkiewicz-Zygmund’s strong law of large numbers is extended to weighted sums of negatively associated random variables.
Furthermore, we investigate various limit properties of Cesàro’s and Riesz’s sums of negatively associated random variables.
Some of the results in the i.i.d. setting, such as those in Jajte (Ann. Probab. 31(1), 409–412, 2003), Bai and Cheng (Stat. Probab. Lett. 46, 105–112, 2000), Li et al. (J. Theor. Probab. 8, 49–76, 1995) and Gut (Probab. Theory Relat. Fields 97, 169–178, 1993) are also improved and extended to the negatively associated setting.

Let {Xn, n1} be a sequence of stationary negatively associated random variables, Sj(l)=∑li=1 Xj+i, Sn=∑ni=1 Xi. Suppose that f(x) is a real function. Under some suitable conditions, the central limit theorem and the weak convergence for sums
are investigated. Applications to limiting distributions of estimators of Var Sn are also discussed. 相似文献
