The variogram is given by cgram(0)-cgram(h)
and
lrvgram(h)[,i,j]==vgram(h)[,i,i]+vgram(h)[,i,j]-2*vgram(h)[,i,j]
.
The logratio-variogram is the set of variograms of each of the pairwise
logratios. It can be proven that it carries the same information as a
usual multivariate variogram. The great advantage is that all the
funcitions have a direct interpreation and can be estimated even with
(MAR) missings in the dataset.
