lscvplot
|
Compute the LSCV plot.
|
lscvplot
|
Usage:
lscvplot(..., alpha)
Description:
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:
- ...
- 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.
Value:
An object with class "gcvplot", containing the smoothing
parameters and LSCV scores. The actual plot is produced using
plot.gcvplot.
