Usage
ICIsmooth(y, hmax, hinc = 1.45, thresh = NULL, kern = "Gaussian", m = 0, sigma = NULL, nsector = 1, sector = 1, symmetric = FALSE, presmooth = FALSE)
Arguments
y
Object of class "array" containing the original (response) data
on a grid
hinc
factor used to increase the bandwidth from scale to scale
thresh
threshold used in tests to determine the best scale
kern
Determines the kernel function.
Object of class "character" kernel, can be any of
c("Gaussian","Uniform","Triangle","Epanechnicov","Biweight","Triweight").
Defaults to kern="Gaussian".
m
Object of class "integer" vector of length length(dy)
determining the order of derivatives specified for the coordinate directios.
sigma
error standard deviation
nsector
number of sectors to use. Positive weights are restricted to the sector
selected by sector
sector
Object of class "integer" between 1 and nsector. sector used.
symmetric
Object of class "logical" determines if sectors are symmetric with respect to the origin.
presmooth
Object of class "logical" determines if bandwidths are smoothed
for more stable results.
