Hi list/Edzer,

I am trying to determine errors in the krige output and can't find any
documentation on the details of the variance output of krige {gstats}
(variable var1.var of krige output).

How is this variance defined? Basically I am after a way to calculate
other statistics like N, standard error, CV or a probability to describe
the uncertainty of the krige output.

All help appreciated
