摘要
讨论了双重时间序列模型xt=θtxt-1+εt(1)的平稳解存在的条件,这里,θt是平稳的自回归滑动平均ARMA(P,q)序列。并且,在θt是一阶自回归序列AR(1)时,给出模型(1)有平稳解的显式条件。
The existence for stationary solution to double stochastic time series model isx t=θ tx t-1 +ε tWhere,θ t is ARMA(P,q) series. The explit condition of the exitence for stationary solution to DSAR(1)-AR(1) is given.
