Local Spatial Autocorr.

Local Spatial Autocorr.


Pockets of spatial instability

Portions of a map where values are correlated in a particularly strong and specific way

[High-High] + SA of high values (hotspots)

[Low-Low] + SA of low values (coldspots)

[High-Low] - SA (spatial outliers)

[Low-High] - SA (spatial outliers)


Local Indicators of Spatial Association

Statistical tests for spatial cluster detection Statistical significance

Compares the observed map with many randomly generated ones to see how likely it is to obtain the observed associations for each location
