Global Thresholding of SW Coefficients

Share:

Description

This function calculates global thresholded SW coefficients.

Usage

1
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"’.

Details

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

Value

talpha

global thresholded SW coefficients
