Estimation of the parameters of the Markovian representation of the autoregressive-moving average model

Abstract

Tuan (1978) discussed the approximate maximum likelihood estimation of the parameters of the Markovian representation of the autoregressive-moving average model. He considered an indirect method, using the equivalent quasiautoregressive moving average form, the parameters of which are in one to one correspondence with those of the Markovian representation. A method of finding exact joint maximum likelihood estimates of the parameters and the initial state of the process is described here.
