Hi, I am trying to compute an autoregressive model incorporating fixed effects and reciprocal paths between time dynamic components of two variables. I runned the model for three-waves data, but the model with two-waves data returned an error message (degrees of freedom negative, model not identified). I wonder whether it was possible to compute such a model with only two waves? The model is: X BY x1@1 x2@1; Y BY y1@1 y2@1; X WITH Y; x2 ON x1; y2 ON y1; x1 WITH y1; y2 ON x2; x2 ON y2; Thank you, Stéphanie |

This model is not identified with two time points. |

This is the answer I expected. Thank you. |
