在本文中,我们研究了各种方法来检测协整秩的变量的数量变得很大。我们表明,使用标准的工具将始终导致误导性的推论,在这种情况下,由于过度的大小失真。特别是LR检验往往会产生太多的协整。我们引入了一个新的测试统计量,显示优秀的大小属性在小型和大型系统。此外,我们提出了一个模型选择程序选择协整秩。一个新的准则优于标准的信息理论准则(AIC,BIC)。
In this paper we study various methods for detecting the co integrating rank as the number of variables gets large. We show that the use of standard tools will always lead to misleading inferences in such settings due to excessive size distortions. Particularly the LR test tends to produce too much cointegration. We introduce a new test statistic that displays excellent size properties in both small and large systems. In addition we propose a model selection procedure for selecting the co integrating rank. A new criterion outperforms the standard informationtheoretic criteria (AIC, BIC).
