Specifying spatial correlation Form in nmle
...for each land parcel and
used them in the correlation form like this:
test.exp<-corExp(1, form = ~ X + Y)
test.exp<- Initialize(test.exp,dataset)
However, the correlation Matrix generated does not look right. Here is a
portion of the matrix, in which all correlations are 0:
> corMatrix(pdxspc.exp)[1:5, 1:5]
[,1] [,2] [,3] [,4] [,5]
