poly_orth {PolynomF} | R Documentation |
Generate a list of polynomials up to a specified degree, orthogonal with respect to the natural inner product on a discrete, finite set of x-values with equal weights.
poly_orth(x, degree = length(unique(x)) - 1, norm = TRUE) poly.orth(...)
x |
A numeric vector |
degree |
The desired maximum degree |
norm |
Logical: should polynomials be normalised to length one? |
