... which the optimal kernel function is similar to the optimal kernel function for {x( t)}. In this paper, we prove that the MSE optimal kernel function for any parameterized family of random processes ... remarkably well for every member of the family, except when α is close to zero. In fact, for more than 50% of the members of this family, the use of the k...
