The lscvplot
function loops through calls to the lscv
function (and hence to link{locfit}
), 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.
lscvplot(..., alpha)
An object with class "gcvplot"
, containing the smoothing
parameters and LSCV scores. The actual plot is produced using
plot.gcvplot
.
arguments to the lscv
, locfit
functions.
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.
