mrsfield.comp.thresh.global: Generation of Detailed Fields by Global Thresholding

In SpherWave: Spherical Wavelets and SW-based Spatially Adaptive Methods

Description

This function generates detailed fields based on global thresholding of SW coefficients.

Usage

mrsfield.comp.thresh.global(grid, coef, site, netlab, eta, lam,
K, 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
lam	thresholding value
K	the number of resolution levels to be thresholded in the decomposition
type	the type of thresholding. This can be ‘"universal"’, ‘"probability"’, ‘"fdr"’, ‘"Lorentz"’ and ‘"sure"’.

Value

dfield

detailed fields generated by global thresholding
