question about fitted values from geoR - results 'too good'
...s AIC BIC
> "51.99" "3" "-97.98" "-91.8"
With a difference in AIC of only about 1.
However looking at the predicted values versus the fits for the model
The spatial model fitted values appear to be some how too good.
> cor(fitted.likGRF(m2, spatial=TRUE), td$Crotaphytus)
[1] 0.9934701
> cor(fitted.likGRF(m2, spatial=FALSE), td$Crotaphytus)
[1] 0.2522837
So I don't get how the spatial model with only a delta AIC of 1 can
have a correlation with the dependent variable that is this high. Am I
mis-interpreting the values I...
