It appears to me that whenever I read in the literature about Moran's I having limits between -1 and 1 for row-standardised, symmetric weight matrices, it is typically presented as a "well known fact", but not quoted with a proper source with derivation. I'm looking for such source, since in my field Moran's I isn't often used, therefore I can't assert such facts being "well known".
I did find a derivation in the answer to another question but this is of no use to me because:
- I cannot quote a website,
- I don't want to copy these calculations and take credit for them.
Are there any reliable sources that may be quoted on that statement?
I am aware of de Jong et al. "On Extreme Values of Moran's I and Geary's C" but that doesn't include the statement that I'm looking for.
