The CORR function.

Calculate the correlation coefficient. This standard SQL function may be supported natively, or emulated using DSL.covarPop(Field, Field) and DSL.stddevPop(Field). If an emulation is applied, beware of the risk of "Catastrophic cancellation" in case the calculations are performed using floating point arithmetic.
