Student: Iusupova Farangizbegim Assignment: VAR Estimation and Identification

✅ Overall Assessment

Result: ✅ Pass

Outstanding submission. The code is exceptionally well-structured and detailed. It goes beyond the basic requirements by calculating and visualizing confidence bands (though essentially just markers in this code, the intent is clear), saving results to tables, and providing a thorough automated analysis of the “Price Puzzle”.
