Example of Color Map on Correlations

In this example, you construct and examine a Color Map on Correlations.

1. Select Help > Sample Data Library and open Cherts.jmp.

2. Select Analyze > Clustering > Cluster Variables.

3. Select all continuous variables and click Y, Columns.

4. Click OK.

5. Close the Cluster Summary and the Standardized Components reports.

6. Place your cursor over the cell in the second row and first column of the Color Map.

A tooltip appears, showing that the variables corresponding to this cell are La and Eu, and that their correlation is 0.822829.

Figure 16.4 Color Map on Correlations for Cherts.jmp 

The Cluster Members report shows that there are four variables in Cluster 1. In the Color Map on Correlations, the four-by-four square of cells in the upper left corner that corresponds to these five variables shows a distinct pattern of positive correlations. The color map also shows patterns of positive correlations for the variables in Clusters 2, 4, and 5. The two-by-two square of cells in the lower right corner of the color map that corresponds to the two Cluster 6 variables shows that they are negatively correlated. See Color Map on Correlations.
