     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.
