Hi, I'm trying to use the "spdep" package function globalG.test() to compute Z-scores using Get-Ord Gi* for a data frame of temperature values for the Northeast (after creating the listw object required), however I keep receiving an error explaining that I can't input negative values. I'm basically trying to mimic ArcGIS' "Hot Spot Analysis" and am wondering if anyone knows of a built-in function or package that can do this or a method that works for you.
I could write a very large program using the Get-Ord local statistic equation, however I'm looking for a more efficient solution.
