对于两个对称α-稳定随机变量(1 <α< 2),我们给出了条件方差存在且有限的充要条件,证明了它有一个与它们的联合分布无关的固定函数形式,描述了它的渐近性态,并说明了它对联合分布的全局依赖性.
For two symmetricα-stable random variables with 1 <α< 2 we find a necessary and sufficient condition for the conditional variance to exist and be finite, we show it has a fixed functional form independent of their joint distribution, we describe its asymptotic behavior and we illustrate its global dependence on the joint distribution.
