The calling sequence for lcv
matches those for the
locfit
or locfit.raw
functions.
The fit is not returned; instead, the returned object contains
likelihood cross validation score for the fit.
The LCV score is exact (up to numerical roundoff) if the
ev="cross"
argument is provided. Otherwise, the influence
and cross validated residuals
are computed using locfit's
standard interpolation based approximations.
