LOCFIT: R and S-Plus Help

lscvplot(..., alpha)

The lscvplot function loops through calls to the lscv function (and hence to linklocfit), using a different smoothing parameter for each call. The returned structure contains the LSCV statistic for each density estimate, and can be used to produce an LSCV plot.

...

arguments to the lscv, locfit functions.

alpha

Matrix of smoothing parameters. The lscvplot function loops through calls to lscv, using each row of alpha as the smoothing parameter in turn. If alpha is provided as a vector, it will be converted to a one-column matrix, thus interpreting each component as a nearest neighbor smoothing parameter.

An object with class "gcvplot", containing the smoothing parameters and LSCV scores. The actual plot is produced using plot.gcvplot.
