Description

This function generates detailed fields based on level-dependent thresholding of SW coefficients.

Usage

mrsfield.comp.thresh.level(grid, coef, site, netlab, eta, K, 
policy, Q, type)

Arguments

grid

grid points of extrapolation sites in radian

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

policy

threshold technique. At present the possible policies are ‘"universal"’, ‘"fdr"’ and ‘"Lorentz"’.

Q

parameter for the false discovery rate of ‘"fdr"’ policy.

type

the type of thresholding. This can be ‘"hard"’, ‘"soft"’ or ‘"Lorentz"’.

Details

This function calculates level-dependent thresholded detailed fields.

Value

dfield

level-dependent thresholded detailed fields
