Dear colleagues,
I am approaching the hotspot analysis for the first time.
My main goal is to understand the advantages and disadvantages of different methods used for the hotspot analysis (e.g., Moran I, Getis, etc.).
Maybe you can help me to better understand how Getis G* works (https://pro.arcgis.com/en/pro-app/latest/tool-reference/spatial-statistics/h-how-hot-spot-analysis-getis-ord-gi-spatial-stati.htm).
There is something I do not understand. Imagine I have occurrence data points (i.e., points in a map with the same value as each value indicates an occurrence event). Is it necessary to aggregate the occurrence data? What I mean is, if all input values are "1", can Getis G* still work or I should aggregate data in the same grid prior to the analysis?
Thank you very much in advance,
Chiara
