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.
