Realization of Covariance Sequences
Abstract
This paper examines the problem of positivity in relation to the partial realization of scalar power series. An exact criterion of positivity is proved for second-order realizations. The general case is currently unsolved. Even the special results contained here show that the so-called maximum entropy principle cannot be applied to the realization problem in the naive sense in which it is employed by physicists. It would be better to call this principle a prejudice because it does not fully utilize the information inherent in the data and does not provide a realization with natural (minimal) mathematical properties.
