# VECM model in Eviews with a mix of stationary and non-stationary variables [closed]

I have three I(3) variables and three I(0) variables.

I found that I(3) variables are co-integrated and my dependent variable is one of I(3)s.

When I tried to build a VECM model in Eviews, Eviews will automatically difference all the variables including the stationary ones.

So I am wondering if there is a way I can run a VECM model with both stationary and non-stationary variables on Eviews?

In R you can do cumulative summation via the function cumsum. I am sure it is also possible to do cumulative summation in EViews, you just need to find the right function, or you can write a loop that does it.
