Dear All,
I have found in the poly help this sentence:

The orthogonal polynomial is summarized by the coefficients, which can be
used to evaluate it via the three-term recursion given in Kennedy & Gentle
(1980, pp. 343?4), and used in the predict part of the code.

My question: which type of orthogonal polynomials are used by this function?
Hrmite, legendre..

From the help page:

     Returns or evaluates orthogonal polynomials of degree 1 to
     'degree' over the specified set of points 'x'.

If you don't know what orthogonal polynomials over a finite set are, please look them up in the references given. Hermite (sic), Legendre (sic) etc are for continuous variables with inner-products given by integrals.

TIA
Giovanni
