## ABSTRACT

Each of the terms in this matrix may also be written as a covariance, giving

Using g and G as the general subscripts designating tests, where g varies from 1 to K and G varies from I to L, we can write the sum of all the terms in the foregoing matrix as follows :

Since the N is a constant for all terms, we may take it outside, writing the following equation for the numerator term of equation 1 .
