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
