On the finite sample distribution of residual autocorrelations in autoregressive-moving average models
Graduate School of Business, University of Chicago Illinois
We examine by simulation the finite sample properties of tests of model adequacy based on individual residual autocorrelations, and of portmanteau statistics based on several residual autocorrelations, for autoregressive-moving average models. Both nonseasonal and seasonal models are considered.
