Crime and property DSAMs are cross-correlated and form a hierarchical structure.

<p>The matrix plot shows the value of the Pearson correlation coefficient (<i>ρ</i>_<i>ij</i>) evaluated for each combination of crime and property DSAM (<i>i</i> and <i>j</i>). The number inside each cell is the coefficient value and the color code also refers to <i>ρ</i>_<i>ij</i> (blue indicates negative correlation, while red is used for positive correlations; the darker the shade, the stronger the correlation). The insets indicated by arrows show examples of relationships among crime and property DSAMs. Upper and right-side panels are dendrograms constructed via the hierarchical clustering algorithm (based on the distance ).
