## Abstract

It should be noted that for linear bivariate models, the third order cross moments γ

xy (k, 1)= 0 for all k and 1. Hence looking at a table of the third order cross moments one can

easily distinguish bivariate bilinear models from linear bivariate models (assuming the

distribution of noise is Gaussian and series xt had been prewhitened). Again, one can also

distinguish between Tables 2, 3, and 4, ie, between diagonal, subdiagonal, and

superdiagonal bivariate bilinear models by looking at these tables. It may also be possible to

distinguish the lags of the particular model by carefully looking at the table. It may be more

interesting to look at the third order cross moment table for a few more general bivariate

bilinear models.
