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.

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
