mrs.comp.thresh.global: Global Thresholding of SW Coefficients
Description
This function calculates global thresholded SW coefficients.
Usage
mrs.comp.thresh.global(coef, site, netlab, eta, K, lam, type)
Arguments
coef
coefficients of multi-scale SBF's
site
grid points of observation sites in radian
netlab
vector of labels representing sub-networks
eta
bandwidth parameters for Poisson kernel
K
the number of resolution levels to be thresholded in the decomposition
lam
thresholding value
type
the type of thresholding. This can be `"universal"', `"probability"', `"fdr"', `"Lorentz"' and `"sure"'.
Value
talphaglobal thresholded SW coefficients
Details
For selective reconstruction, this function performs thresholding SW coefficients according to several approaches.
