If you knew how to use the function correctly, I suppose that it would be reasonable to expect you to trust its output, at least within the limits of uncertainty.

Perhaps you could post the code that led you to be so scornful about the efforts of whoever did create the function.

It's been my experience that users are often quick to blame the software for their own faulty code. I had no problem obtaining reasonable predicted values for the data.
