polyS: Auxiliary support for the GAMLSS

In gamlss: Generalized Additive Models for Location Scale and Shape

Auxiliary support for the GAMLSS

Description

These two functions are similar to the poly and polym in R. Are needed for the gamlss.lo function of GAMLSS and should not be used on their own.

Usage

polyS(x, ...)
poly.matrix(m, degree = 1)

Arguments

x	a variable
m	a variable
degree	the degree of the polynomial
...	for extra arguments

Value

Returns a matrix of orthogonal polynomials

Warning

Not be use by the user
