Dear all,
I'm trying to estimate the variance of a global abundance estimation computed
by kriging interpolation and I am stuck.
One can easily retrieve the variance at each prediction location (either using
the package gstat, geoR or automap) using expressions similar to:
>kriging_object$krige.var
or >kriging_object$var1.var
but, in fact, I have no idea how these variance values are computed.
Could anybody tell me how is it computed or suggest some reference material?
Could this question be inappropriate for this list in which case I would also
apprieciate if someone could tell me where to ask it.
Cheers,
Pilar
