Abstract

This paper presents a new approach for the optimization of autoregressive moving average parameters estimation. We prove that the log likelihood function of the process is almost surely equal to a polynomial of order two. Thereafter, using the methods of least squares, our function will be approximated by a polynomial of order two which will be used to calculate an estimation of the maximum.
