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

talpha

global thresholded SW coefficients

Details

For selective reconstruction, this function performs thresholding SW coefficients according to several approaches.
