摘要:

本文分析了二维VAR(1)模型分量的乘积。对于引入的时间序列,我们推导了自协方差函数的一般公式,并研究了VAR(1)模型分量之间交叉依赖的不同情况下的性质。理论结果,然后说明在模拟研究的两种类型的二元分布的残差序列,即高斯和学生的t。我们还显示了一个可能的实际应用所获得的结果的基础上,从电力市场的数据。

英文摘要:

In this paper we analyze the product of bi-dimensional VAR(1) model components. For the introduced time series we derive general formulas for the autocovariance function and study its properties for different cases of cross-dependence between the VAR(1) model components. The theoretical results are then illustrated in the simulation study for two types of bivariate distributions of the residual series, namely the Gaussian and Student's t. We also show a possible practical application of the obtained results based on the data from the electricity market.
