Abstract
An essential ingredient of any time series anatysis is the estimation of the modcl parameters. The main objective of this paper is to develop a convenient Rayesian technique for estimation which can be used to analyze ‘seasonal autoregressive moving average processes. The foundation of the proposed approach is to approximate the conditional likelihood by a normal-gamma distribution on the parameter space; Based on the approximated conditional likelihood function, the marginal posterior distribution of the coefficients of the model is approximated by a t distribu- tion, and the marginal posterior distribution of the model precision is approximated by a gamma distribution. The proposed technique is illustrated by some numerical examples.
