Generate the RMSPE value, which is given by the radial basis function with smoothing parameter eta and robustness parameter rho.

param |
vector starting points (eta and rho respectively) for searching the RMSPE optimum. |
formula |
formula that defines the dependent variable as a linear model of independent variables; suppose the dependent variable has name z, for a rbf detrended use z~1, for a rbf with trend, suppose z is linearly dependent on x and y, use the formula z~x+y (linear trend). |
data |
SpatialPointsDataFrame: should contain the dependent variable, independent variables, and coordinates. |
n.neigh |
number of nearest observations that should be used for a rbf prediction, where 'nearest' is defined in terms of the spatial locations |
func |
radial basis function model type, e.g. "GAU", "EXPON", "TRI", "TPS", "CRS", "ST", "IM" and "M", are currently available |
returns the RMSPE value
