Usage:

lcvplot(..., alpha)

Arguments:

...

arguments to the lcv, locfit functions.

alpha

Matrix of smoothing parameters. The aicplot function loops through calls to lcv, 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.

Value:

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

Examples:

data(ethanol)
plot(lcvplot(NOx~E,data=ethanol,alpha=seq(0.2,1.0,by=0.05)))
