3、原版书time-series第5题,答案说The DW statistic cannot be appropriately used for a regression that has a lagged value of the dependent variable as one of the explanatory variables. To test for serial correlation, we need to examine the autocorrelations. 为什么说DW检验不能用在有滞后期的自变量归回中,为什么只能用AR?

同学你好,DW只用于线性回归模型,自回归使用T检验
