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
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
correct.diagonal
multiplicative correction factor to be applied
to partial sills of direct variograms only; the default value, 1.0, does
not correct. If you encounter problems with singular covariance matrices
during cokriging or cosimulation, you may want to try to incre
