Range of Moran's I

[Patrick Yang]

Dear All,

 

I remember global and local Moran's I in the range [-1,1].

However, Tiefelsdorf and Boots (1997) indicates the feasible range is (-n)⁄((2√(d_i)))  , where d_i is the local linkage.

Tiefelsdorf, Michael, and Barry Boots. 1997. A Note on the Extremities of Local Moran's Iis and Their Impact on Global Moran's I. Geographical Analysis 29 (3):248-257.

Some people aslo criticise that [-1,1] is wrong.

 

I am so confused and spending couple of days to find references. Surprisingly, quite few indicate [-1,1]. Which one is true?

 

I understand there might be some extreme values in usual cases.

 

Appreciate if anyone can help.

With best regards,

Zhenshan
