Dear All,
I am working with a multivariate geostatistics. In
determining whether the semivariogram or
cross-semivariogram follows a linear coregionalization
model or not...must the spatial range be the same?
For instance, I have semivariogram and
cross-semivariogram from 2 different variables as
follow:
gamma1(h) = 11 nug(h) + 39 sph(h/60)
gamma1(h) = 9 nug(h) + 15 sph(h/100)
gamma12(h)= 14.5 sph(h/80)
If I consider only the variance-covariance components,
such models follow the positive-semi definite
condition. But how about the different spatial range I
have in each semivariogram-cross semivariogram? Is it
essential in a linear coregionalization model?
Thank you for your attention.
Regards,
Nur Heriawan
