Hello,

I'd like to estimate a multi-level AR model, in which Y at t is predicted by Y at t-1 and X at t. This model is equivalent to Figure 5 in McNeish & Hamaker (2019).

If I include the INTERVAL option, I receive the following error:

When expanding time series data with the TINTERVAL option, all variables on
the within level should be dependent variables. Problem with: X

I don't receive an error if:
- Estimate a multi-level AR model with a predictor, as described above, without using the TINTERVAL function.
- I estimate a model with an autoregressive effect for Y and using TINTERVAL (without any other predictors)
- Estimate a multi-level VAR model with 2 outcomes (Y and X), and using the TINTERVAL function.

Is it correct that the TINTERVAL function could only be used to estimate multi-level VAR models, but cannot be used to estimate multi-level AR models with any other predictors in the model?

Thank you in advance.
