Update of bug #65893 (group octave):
Status: None => Invalid / Not an Octave
Bug
Open/Closed: Open => Closed
_______________________________________________________
Follow-up Comment #2:
This is expected. Here is an excerpt of the doc
...
When the third output, MU, is present the original data is centered
and scaled which can improve the numerical stability of the fit.
The coefficients P are associated with a polynomial in
'XHAT = (X - MU(1)) / MU(2)'
where MU(1) = mean (X), and MU(2) = std (X).
...
Closing report as invalid/not a bug.
