spatial structure of residuals in nlme mixed model
im trying to asses about the diference in puting the spatial estructure in
a mixed linear model.
What i need to do is to compare the actual distribution of the residuals of
two models, one that consider the correlation and one that not.
until now, what i could do is to cheq the existance of that structure by
computing the semivariogram to the residuals.
the question is how can i do the next step and krige this residuals in
order to get a map of predicted values and variance values?
im used to do it wity gstat package but i cant figured out with an object
of class "lme"
