lscv

The calling sequence for <code>lscv</code> matches those for the
 <code>locfit</code> or <code>locfit.raw</code> functions.
 Note that this function is only designed for density estimation
 in one dimension. The returned object contains the
 least squares cross validation score for the fit.
The computation of \(\int \hat f(x)^2 dx\) is performed numerically.
 For kernel density estimation, this is unlikely to agree exactly
 with other LSCV routines, which may perform the integration analytically.
