Description Usage Arguments Details Value References See Also

This function calculates field and density with Multi-sale SBF's.

1	sbf.comp(point1, point2, site1, site2, coef, netlab, eta, p0)

`point1`	latitude of extrapolation sites in radian
`point2`	longitude of extrapolation sites in radian
`site1`	latitude of observation sites in radian
`site2`	longitude of observation sites in radian
`coef`	coefficients of multi-scale SBF's
`netlab`	vector of labels representing sub-networks
`eta`	bandwidth parameters for Poisson kernel
`p0`	specifies starting level for extrapolation. Among resolution levels 1, …, L, resolution levels p0+1, …, L will be included for extrapolation.

For a given field, this function provides a multiscale SBF representation

T(x) = ∑_{l} ∑_{j} β_{l,j} G_{l}(<x, x_j>),

where G_{l}() denotes a SBF with bandwidth h_l at multiresolution level l.

`aa`	a multiscale SBF field on observation's locations
`bb`	density on observation's locations
