注意到分数稳定过程的样本性质和分布特征都密切关联于其分数参数,本文进一步刻画分数稳定过程关于分数参数的正则性及其对过程协差的影响.
In this paper, notice the sample and distribution properties of fractional stable processes related to the fractional parameter, we investigate the regularity with respect to fractional parameter and its' influence on the a-eovarianee.
