14.4.2 Anselin Local Moran's I

Anselin Local Moran's I is used to analyse the autocorrelation of provinces based
on electricity consumption. A positive value for I indicates that the given feature is
surrounded by features of similar values. In its most basic form, Anselin Local
Moran's I uses the following equation (Bailey and Gatrell 1995; Anselin 1995;
Mitchell 2005):

n

( )

∑ ≠

I = w x − X (14.3)

where

x is an attribute for feature i , X is the mean of the corresponding attribute,

w ,

is the spatial weight between feature i and j , and
