Hi, I wanted to try GWR and I'm confused on the definition of bandwidth. Which will be better to use fixed or the adaptive one?
Please read the references carefully. This is explained by Fotheringham et al. in the GWR book (2002). However, never think of using GWR, especially for anything inferential, without first reading and grasping Paez et al. (2011).

Also, is there a way to compute for the deviance explained by the model just like the one's we get when we do GAM? I want to compare the two based on this metric. Or better yet, are there other metrics to evaluate performance between these two model types? Thank you very much for any insight on this.
