Autoregressive moving average (ARMA)

arma autoregressive moving average

Hello, can anybody tell me where I can find a good tutorial on estimation and algorithm for the calculation of the coeficients of autoregressive moving average models?

search for google by ARMA spectrum estimation, you will find enough information.

To be more precise, I need this for biosignal processing.

The first document is a paper with the following abstract:

Abstract. In many practical situations, an experimenter is interested in the behavior of a process at different time scales T. In this paper it is shown that autoregressive (AR) parameter estimation and order selection can be reformulated to find the best model for the signal properties at interval T. A comparison between AR modeling at interval T and standard AR modeling shows that modeling at interval T can be more accurate in the reduced frequency interval as a result of better order selection. More accurate results can be expected when the model order selected with standard AR analysis is lower than the true order. This occurs when the true process is an AR process with a number of insignificant trailing parameters, or when the true process is AR(∞), e.g. due to additive noise in the data.


The second document provides the basics to AR Models.

The order in which the documents were appeared on the board in the reverse. The ARMA_Model.pdf actually the one that gives you the basics of ARMA processes. The other one is the paper. Sorry!

AR are the poles in DSP
MA are the zeros in DSP
