Can't seem to find this anywhere. How is the R2 in the output report generated? It's not the mean/median or other statistic describing the range of local R2s that GWR produces. How can you report a single R2 for GWR?
Thanks for any help with this, and sorry if it's somewhere obvious, just can't seem to find it!
