lcv {locfit}R Documentation

Compute Likelihood Cross Validation Statistic.


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.
