[R-sig-Geo] cross-variograms and relationship strength

[Michael Hewson]

Please excuse this basic question - I'm a bit befuddled.

If I have two cross-variograms - both with the same two variables.
Both sill at about the same range.
One has a higher cross-semivariance value at that range.
Does that mean it has a "stronger" relationship - in a correlation sense? Or does the greater value for cross-semivariance indicate more "variance" hence less strength? Or can one not make any judgement on relationship strength from the cross-semivariance sill?
