- 1. P-value from ANOVA analysis of mean values across census regions.
- 2. Dissimilarity and isolation indices calculated with a spatial egocentric neighborhood defined by biweight kernel with specified bandwidth.
- 3. Dissimilarity and isolation indices calculated with the census tract as the local/neighborhood area of interest
