As presented, dynamic factor model is only dynamic in the state equation. It can be generalized to have dynamics in the measurement equation as well, i.e. X t depending on current and past values of f t. This should not be di cult to implement as such model would be eventually reduced to (1). 5. Currently, there is no automated testing for ...
