I don’t understand the specific meaning of these five parameters in bvar-a-la-sims.pdf ![image](https://forum.dynare.org/uploads/default/original/3X/0/b/0b7011d380f6802a9eaee3c068d30057ac3776e5.png) Are they the same with _RATS 10 Users Guide_ ? If that’s the same what’s the exact expression for Omega? ![image](https://forum.dynare.org/uploads/default/original/3X/d/b/db7ef80a45fc6bf26aea186d7f5fd719d4878c38.png) ---
