在做Johansen协整检验时，会出现一个窗口，有6个被选框要求选择。分别是：

No intercept or trend in CE or test VAR

Intercept(no trend)in CE-no intercept in VAR

Intercept（no trend）in CE and test VAR

Intercepr and trend in CE-no trend in VAR

Intercept and trend inCE-linear trend in VAR

Summarize all 5 sets of assumptions

哪位达人能告诉我如何选择呢？谢谢！
