报告摘要: Let $X=\{X_n: n\in\mathbb{N}\}$ be a long memory linear process in which the coefficients are regularly varying and innovations are independent and identically distributed and belong to the domain of attraction of an $\alpha$-stable law with $\alpha\in (0, 2)$. Then, for any integrable and square integrable function $K$ on $\mathbb{R}$, under certain mild conditions, we establish the asymptotic behavior of the partial sum process $${\sum\limits_{n=1}^{[Nt]}[K(X_n)-E K(X_n)]: t\geq 0}$$ as $N$ tends to infinity, where $[Nt]$ is the integer part of $Nt$ for $t\geq 0$. An application to the kernel entropy estimation of the long memory linear process will be given.
