[Bug] #2353

Open bhurley6ehs opened 3 years ago

bhurley6ehs commented 3 years ago

Hey all:

I have seen the same number, 5.17598e-005 for a concerning number of returns for datasets. Two datasets with no relation both say this is the correction value, on both datasets, for both the Bonf. and the FDR.

Ideas?

Hi Dr. Anselin:

966 grid cells. See attached. Distribution is very skewed though if that matters. Lots of low values.

Yes: Bonferroni = alpha / n. FDR is often the same.

Alright. For our edification, ArcGIS Pro persists with the same errors from ArcMap. I'm comparing the two as I finish a lab, but I've moved my class to GeoDa.

Thank you!
