eta.comp: Calculation of Bandwidth Parameters of Poisson Kernel/SBF's

Description Usage Arguments Details Value References See Also Examples

Description

This function calculates bandwidth parameters of SBF's induced by Poisson Kernel.

Usage

1

Arguments

netlab

the index vector of network level

Details

The bandwidths h_l of SBF's are chosen as follows

h_{L-1} = e^{-ρ_l}, l = 1, 2,…, L-1,

where ρ_l = ρ^{*} / 2^l. The ρ^* is obtained from the bandwidth of the coarsest network level L, h_L, that is

ρ^* = -\log h_L.

Note that h_L is obtained from the function bandwidth.

Value

eta

bandwidth parameters for Poisson kernel/SBF's
