Residual-Based Tests for Normality in Autoregressions: Asymptotic Theory and Simulation Evidence
自回归模型中基于残差的正态性检验:渐近理论与模拟证据
Existing results for the asymptotic validity of the Jarque-Bera test in vector autoregressive (VAR) models assume stationarity. In applied work, however, researchers often work with possibly integrated and cointegrated process. We prove the asymptotic validity of the Jarque-Bera test for vector error-correction (VEC) models and for unrestricted VAR models with possibly integrated or cointegrated variables. We also propose the use of bootstrap critical values in stationary…
