I am trying to estimate Non-ARDL model. However, in order to make Nonlinear ARDL model through Add-ins, I was faced with this error message attached. I am using Eviews 9 but I have already downloaded the NARDL. Attached is the evidence of the error.
1. How do I over come this error?
2. If I intend estimating non-zero threshold value, what do i do?
3. If I intend estimating zero threshold value, what do i do?
Thank you!
