Hi,

 

I am looking forward to obtain a correlation and covariance matrix with the variables I have for a data, I know I have to use variable cluster node.

 

Kindly help me understand, how to use this node and see the output( which part of the output page provides information)

 

Thank you,

Prajna

The Variable Clustering node produces the correlations by default when you run the node.

 

After the node completes, view the results.

In the Results window, select View -> Model -> Variable Correlation.  A heat map is displayed.

To view the values of the heat map, click the Table icon, and a Table Variable Correlation window is displayed.

From that window, you can select File -> Save As if you want to create a SAS data set that contains the correlations.

 

The covariances are not output.
