## 1 Identification of *PanelVAR* model

Assume there are n_i items measured by n_t times, then there are n_v = n_t \times n_i. For example, if 3 items are measures by 3 times, there will be 9 measures. Following figure shows the example of n_t =2 and n_i = 3. In total, there are 24 parameters and 6 * (6+1) / 2 + 6 = 27 observations.
