Usage

gamlss.ra(x, y, w, df = NULL)

Arguments

x

the explanatory design matrix

y

the response variable

w

iterative weights

df

effective degrees of freedom

Value

• Returns an list with
• fitted.values
  fitted values
• residuals
  residuals
• var
  variances of the fitted values

  the value of the smoothing parameter
• coefSmo
  the coefficients from the smoothing fit
• varcoeff
  the variance of the coefficients
