Cauchy’s Means of Levinson Type

In this paper we introduce Levinson means of Cauchy’s type. We show that these means are monotonic.

Periodic Levinson-Durbin algorithm for entropy maximization

One gives a recursive algorithm for the computation of the first and second order derivatives of the entropy of a periodic autoregressive process with respect to the autocovariances. It is an extension of the periodic LevinsonDurbin algorithm. The algorithm has been developed for use at one of the steps of an entropy maximization method developed by the authors. Numerical examples of entropy ma...
