gamlss.fp: Support for Function fp()

Description

Those are support for the functions fp() and pp. It is not intended to be called directly by users.

Usage

gamlss.fp(x, y, w, npoly = 2, xeval = NULL)
gamlss.pp(x, y, w)

Arguments

x

the x for function gamlss.fp is referred to the design matric of the specific parameter model (not to be used by the user)

y

the y for function gamlss.fp is referred to the working variable of the specific parameter model (not to be used by the user)

w

the w for function gamlss.fp is referred to the iterative weight variable of the specific parameter model (not to be used by the user)

npoly

a positive indicating how many fractional polynomials should be considered in the fit. Can take the values 1, 2 or 3 with 2 as default

xeval

used in prediction

Value

• Returns a list with
• fitted.values
  fitted
• residuals
  residuals
• var
• nl.df
  the trace of the smoothing matrix
• lambda
  the value of the smoothing parameter
• coefSmo
  the coefficients from the smoothing fit
• varcoeff
  the variance of the coefficients
