Error message dfunit

[Gilbril]

Dear Tom,

I use the DFUNIT procedure in a routine by default to check the stationarity of the variables . However, I often get the following error message:

## X13. Redundant Restrictions. Using 0 Degrees, not 2

What does this mean and how to turn it off?

Thanks

Paul

That would require a rather serious problem with the data (like all zeros or perhaps some massive outlier that causes calculations to overflow).
