As I already pointed out
higher variance => higher lagrangian multiplier
so that some of the efect is cancelled out anyway.
We (Geostokos) use the following as a filter:
ygiagam (proven resource): kriging variance should be
less than original sample variance (total sill) less
within block variance
probable resource: kriging variance should be less
than twice the above and at least 4 samples should be
used in the estimation
These are fairly arbitrary but have proved sound over
the last 10-15 years.
