Hello Maurizio,
Mostly Variance Inflation Factor (VIF) criteria is applied, which is avaiable
is all standard R-packages that offer performing regression.

hi people,
My objective is to perform K-fold cross validation for the spdep spautolm (CAR)
and spgwr GWR model objects, to evaluate the models predictive performance
(using model predictions and sampled data). For this, I have been searching for

Hi list members,
It is wekk known that OK tends to smooth the spatial variation of a variable;
in particular they overestimate small values and underestimate large values.
What should I percieve if I am getting a revserse effect after krging i.e.
underestimated small values and overestimated
Hi list fellows,
Do someone have any idea to calculate the standard deviation of GWR predictions
(prediction variances), similary as we calculate with the sqrt of prediction
variance provided by kriging?
Would be thankful for any help?
Best regards
Imran
Hello,
Can anybody confirm if the prediction variance of GWR calculated as
sqrt(var(mod.gwr$SDF$pred.se)) is right?
Thanks and regards,
