fit.lmc: Fit a Linear Model of Coregionalization to a Multivariable Sample Variogram

Description

Fit a Linear Model of Coregionalization to a Multivariable Sample Variogram; in case of a single variogram model (i.e., no nugget) this is equivalent to Intrinsic Correlation

Usage

fit.lmc(v, g, model, fit.ranges = FALSE, fit.lmc = !fit.ranges, ...)

Arguments

v

multivariable sample variogram, output of variogram

g

gstat object, output of gstat

model

variogram model, output of vgm; if supplied this value is used as initial value for each fit

fit.ranges

logical; determines whether the range coefficients (excluding that of the nugget component) should be fitted; or logical vector: determines for each range parameter of the variogram model whether it should be fitted or fixed.

fit.lmc

logical; if TRUE, each coefficient matrices of partial sills is guaranteed to be positive definite

...

parameters that get passed to fit.variogram

Value

• returns an object of class gstat, with fitted variograms;
