Does anyone know the formula for calcuating Local Moran I, in ENVI.
I created a sample 5x5 image and calculated "Local Moran I" in ENVI. Parellay I calculated local moran I manually in Excel. I really donot understand what went wrong, in ENVI the values are too low, and no way matching up with the results that I got manually(seriously I tried 10 time, using the formulas from text book).
Any help is appriciated.

Hi naveen,
Well, I checked in the ENVI Help and in there, i.e.:
Explore Imagery > Statistics > Local Spatial Statistics
They based the information and the Local Moran I index in the following books:
Anselin, L., 1995. Local Indicators of Spatial Association – LISA. Geographical Analysis 27(2):93-115
Getis, A. and J.K. Ord, 1992. The Analysis of Spatial Association by Use of Distance Statistics. Geographical Analysis 24(3):189-206.
Cheers,
Fernando

Thanks Fernando,
I tried to study the literarture, they were really intimidating and seemed like a decent amount of time is required to understand them.
