Method of Moments Estimators for the Moving Average Coefficients in an ARMA (p,q) Process.
Abstract
The standard procedure for computing the moving average method of moments parameter estimates for an ARMA process involves the numerical solution of a system of non-linear equations. In this paper it will be shown how the so-called inverse autocorrelations introduced by Cleveland can be utilized to compute the moving average parameter estimates as the solution to a system of linear equations, and that the method is faster and more accurate than solving the non-linear equations alluded to above. In addition, the procedure described below ensures that an invertible solution is obtained. (Author)
