Comparing two Hot Spot Analysis (Getis-Ord Gi*)

Discussion created by peter.geissbuehler on Jun 22, 2012
I have analyzed with the HotSpot methodology Hot Spot Analysis (Getis-Ord Gi*) two insurance portfolios (A and B) with losses from a specific windstorm (ZIP). These two analyses show the host spots where highest losses were observed as well as lowest loss.
Now, I would like to compare these two hot spot analyses using the Z score and p-value to identify how different these two portfolios are.
Question: Is it correct to multiply the p-values of portfolio A and B to get the difference (standard distance)?

Any help is appreciated.
Thanks a lot
