Compute a correlation or a covariance matrix.
Compute a correlation or a covariance matrix. This action has two input pins: The first input pin is the Main Data Table. The second input pin defines the columns that are included inside the correlation/covariance matrix: i.e. it contains the mean of the variables that must be included inside the correlation/covariance matrix.
The data preparation consists of a simple aggregate: Just compute the mean of the variables that you want to include inside the correlation matrix:
