Variables must be analyzed together, that is, they must be combined in some manner to form a composite variable or variate. The most common way to combine variables is by forming a weighted linear composite. Where each variable is weighted in a manner deter-mined by the analysis. This resulting weighted linear composite is known as a variate.
