Linear Transformations and Linear Composites
... Thus, a linear transformation will change the covariance only when both of the old variances are multiplied by something other than 1. If we simply add something to both old variables (i.e., let a and c be something other than 0, but make b = d = 1), then the covariance will not change. Although a l ...
