R: Support for Function fp()

gamlss.fp {gamlss} | R Documentation

## 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
