英文摘要:
We construct a new process using a fractional Brownian motion and a fractional Ornstein-Uhlenbeck process of the Second Kind as building blocks. We consider the increments of the new process in discrete time and, as a result, we obtain a more parsimonious process with similar autocovariance structure to that of a FARIMA. In practice, variance of the new increment process is a closed-form expression easier to compute than that of FARIMA.

中文摘要:
我们以分数布朗运动和第二类分数Ornstein-Uhlenbeck过程为构造块构造了一个新过程。我们考虑了新过程在离散时间内的增量,因此,我们得到了一个与FARIMA过程具有相似自协方差结构的更为简洁的过程。实际上,新增量过程的方差是一个比FARIMA更容易计算的闭式表达式。
