This is support for the functions cs(), and scs().
It is not intended to be called directly by users. The function `gamlss.cs`

is using the R function `smooth.spline`

`gamlss.cs(x, y, w, df = NULL, spar = NULL, xeval = NULL, ...)`

Returns a class "smooth.spline" object with

- residuals
The residuals of the fit

- fitted.values
The smoothing values

- var
the variance for the fitted smoother

- lambda
the final value for spar

- nl.df
the smoothing degrees of freedom excluding the constant and linear terms, i.e. (df-2)

- coefSmo
this is a list containing among others the knots and the coefficients

- x
the design matrix

- y
the response variable

- w
prior weights

- df
effective degrees of freedom

- spar
spar the smoothing parameter

- xeval
used in prediction

- ...
for extra arguments
