摘要
本文主要考虑二维自激门限自回归模型:X(t)=I[X(t-1)∈Ri]AiX(t-1)+ε(t),其中Ai(i=1,2,3,4)为2×2系数矩阵,{ε(t)}为二维i.i.d序列。我们得到{X(t)}为遍历的四个充分条件。
We consider the 2-dimensional model:X(t)=I[X(t-1)∈Ri]AiX(t-1)+ε(t),Where Ai(i=1,2,3,4)are 2×2 matrices of coefficients,{e(t)}is a sequence of i.i.d random variables with mean 0.Some sufficient conditions are given for{X(t)}to be ergodic.
