Create an object of class '>polyX
from transformed X-inputs and standard polynomial.
crpolyXT(varnames, dataXT, d, type = "full")
X-input names. A character vector of length equal to the number of X-inputs.
Transformed X-inputs. A data.frame with as many rows as observations, and which the number of columns is equal or greater than the number of monomials.
Polynomial degree.
Polynomial type: see crpolyX.
