lscvplot {locfit} | R Documentation |
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)
... |
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
.
