I am attempting to model a set of autoregressive crosslag models over 6 occasions, but am running into an error when using one continuous variable and one count outcome. The error is below. Can you specify how to model variances for a count variable:

*** ERROR in MODEL command
Variances for count variables are not currently defined.
Variance given for: S0SROV
*** ERROR in MODEL command
Variances for count variables are not currently defined.
Variance given for: S1SROV
*** ERROR in MODEL command
Variances for count variables are not currently defined.
Variance given for: S2SROV
*** ERROR in MODEL command
Variances for count variables are not currently defined.
Variance given for: S3SROV
*** ERROR in MODEL command
Variances for count variables are not currently defined.
Variance given for: S4SROV
*** ERROR in MODEL command
Variances for count variables are not currently defined.
Variance given for: S5SROV

There is no (residual) variance parameter for a count DV. See our RMA book chapter on count modeling.

Also, for count DVs, WITH statements need to be replaced by a factor measured by both DVs.
