Summary
Let A be an arbitrary matrix with complex entries. It is known that the arithmetic mean of the diagonal elements of AA* is used for the measure of error of the linear predictions of matrix-valued stationary stochastic processes. It can be raised the question what happens if we apply another means of these diagonal elements. In this paper we use the geometric and harmonic means besides the arithmetic one for that purpose.
