Automatic Specification Testing for Vector Autoregressions and Multivariate Nonlinear Time Series Models
向量自回归与多元非线性时间序列模型的自动设定检验
This article introduces an automatic test for the correct specification of a vector autoregression (VAR) model. The proposed test statistic is a Portmanteau statistic with an automatic selection of the order of the residual serial correlation tested. The test presents several attractive characteristics: simplicity, robustness, and high power in finite samples. The test is simple to implement since the researcher does not need to specify the order of the autocorrelation…
