Abstract
For the bilinear time series Xt=βXt‐ket‐l+ev, k≥l, formulas for the first k‐1 autocorrelations of X2t are obtained. These results fill in a gap in Granger and Andersen (1978). Simulation experiments are used to study the applicability of theoretical results and to investigate some more general situations. It is found that if ß is not too small, k and l may be identified using the autocorrelations of X2t. Application to more general situations is also briefly discussed.
