一类非平稳时间序列的周期性
PERIODICAL PROPERTY OF A CLASS NONSTATIONARY TIME SERIES
【摘要】 本文研究了一类非平稳时间序列的稳定性及周期性,得到了它为周期相关序列的充分必要条件,推广了文献[3]的结论.
【Abstract】 in this paper,a Class nonstationary time sequences xt=xt-1+et are studied and a necessary andsufficient conditions with periodically correlated time sequences are developed. The result given by [3] is generalized.
