Re: Problems with HotSpot tool
What you will notice is that if you run the Hot Spot Analysis tool with row standardization or without row standardization, the results will be exactly the same.
That's why that option is disabled. This ONLY applies to the Hot Spot Analysis tool. For Anselin Local Moran's I, row standardization will impact the Index value, but not the Z score. Row standardization has a definite impact on the other tools that include the Row Standardization parameter.
When I first wrote the script for Gi* I stupidly added the Row Standardization parameter (not realizing it has no impact on the results). Unfortunately, once Esri releases a tool we cannot remove parameters (that's so we don't break existing workflows or models). The only thing I could do was to gray out that parameter, which I did. I'm very sorry for the confusion.
Shoot I just checked the documentation and it does not explain this. I will correct this immediately. Thank you for posting your question.
Again, my apologies,
