In SeoncheolPark/SphereWaveu:

Description Usage Arguments Details Value References See Also

This function calculates global thresholded SW coefficients.

1	mrs.comp.thresh.global(coef, site, netlab, eta, K, lam, type)

`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"’.

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