The CORR function.

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