能不能建立一个 一元二次 方程的线性方程 去验证一个结论
比如说结论是一个变量时关于另一个变量的散点图是抛物线形状

这意思是可以么

Hello buddy,
normally there is no one prohibit you from doing that.

But as a practitioner, I seldom to do so.
More often,  we use lineal equation to handle a business issue.

If your conclusion is beyond my description,
just do it,
as long as you can illustrate it clearly,
you are good.

As far as I know,
there is no restriction on your methodology.
Good luck again.

我能不能再问您个问题，VAR模型做完johansan协整检验，怎么看协整方程

Hi buddy,
I must admit that you mentioned something I don't know.

But after searching my relevant experience,
I made a bold guess.

I remember that my professor told me:
I should evaluate the correlation between those independent variables.
If there was a strong correlation between them,
you'd better at least get rid of one.

Or you can delete another one in your next model.

After comparing the p-value, keep the best one.

I don't know whether this is what you want,
just do whatever I could to save your time.
Thank you.
