Square it pi2Example: Brussels Capital Region: Example: Brussels Capital RegionMeasuring Heterogeneity : Measuring Heterogeneity IC: Index of Concentration 3. Sum the squaresBrussels Capital Region (Continued): Brussels Capital Region (Continued) 0.485 0.262 Measuring Heterogeneity : Measuring Heterogeneity IC: Index of Concentration 4. At maximum concentration, IC=1 5. At minimum IC=1/k Note: Value of IC varies with number of categories, kSome other communes: Some other communesComparing Distributions Duncan’s Index of Dissimilarity: Comparing Distributions Duncan’s Index of Dissimilarity For each category, take absolute differences between the proportion in each groupExample: St. Gillis vs Elsene: Example: St. Gillis vs ElseneComparing Distributions Duncan’s Index of Dissimilarity: Comparing Distributions Duncan’s Index of Dissimilarity 2. Sum the absolute differences 3. Divide by 2 4. D is the proportion (or percentage) in each group which has to be reallocated to give the same distribution as in the other groupExample: St. Gillis vs Elsene: Example: St. Gillis vs Elsene Sum = 38.99 D = 19.5Example: Watermaal vs St. Joost: Example: Watermaal vs St. Joost D = 41.6 You do not have the permission to view this presentation.
