Description

An efficient algorithm for computing the exact symbolic inverse of the covariance matrix of n successive observations from an ARMA(p,q) time series is given. The algorithm was derived in in a paper by Zinde-Walsh (1988). Zinde-Walsh, V. (1988). Some exact formulae for autoregressive moving average processes. Econometric Theory, 4, 384-402.
