本文研究了平稳可逆向量自回归滑动平均(VARMA)模型的一个简单的两阶段(Hannan-Rissanen型)线性估计的渐近分布。给出了相合性和渐近正态的一般条件。文中还给出了估计量的渐近协方差矩阵的相容估计,从而可以很容易地构造检验和可信区间。
In this paper, we study the asymptotic distribution of a simple two-stage (Hannan-Rissanen-type) linear estimator for stationary invertible vector autoregressive moving average (VARMA) models in the echelon form representation. General conditions for consistency and asymptotic normality are given. A consistent estimator of the asymptotic covariance matrix of the estimator is also provided, so that tests and confidence intervals can easily be constructed.
