🌍 Week 11 Homework — Feedback

Student: Bakytkul Baltabay Assignment: VAR Estimation and Identification

❌ Overall Assessment

Result: ❌ Fail / Wrong Assignment

Incorrect submission. The homework required you to estimate a VAR using the US Macro Data provided (US_macro_data.csv), but your code simulates artificial data (lines 8-24). While the VAR estimation code itself might be correct for the simulated data, the assignment was to analyze real economic data.

🔍 Task-by-Task Check

Task Description Status Notes
1.1 Data Loading & Cleanup ❌ Critical Error: Simulates fake data instead of loading US_macro_data.csv
1.2 Data Transformation ❌ Not applicable (simulated data)
1.3 Construct Data Matrices ⚠️ Correct for the simulated data, but not for the assignment
1.4 OLS Estimation ✅ Correct OLS code
1.5 Extract A1 Matrix ✅ Correct code
1.6 Residuals & Sigma ✅ Correct code
1.7 Identification (Cholesky) ✅ Correct code
1.8 Compute IRFs ✅ Correct code
1.9 Plot IRFs ✅ Generates plots for the simulated data
1.10 Save Figures ❌ No saveas or exportgraphics command

📈 Technical Implementation

  • Simulation: You simulated AR(1) processes. While this is a good exercise for understanding VARs, it was not the homework task.
  • Code: The VAR estimation logic you wrote is actually correct.

💬 Style & Clarity

  • Comments: Code is commented.

📊 Visual Output Assessment

  • Plots: Plots are generated but reflect artificial data, not the US economy.

✅ Suggestions for Improvement

  1. Follow Instructions: Please use the provided dataset US_macro_data.csv.
  2. Files: Ensure you submit the correct file if this was a mistake.

🎯 Summary

Submission uses simulated data instead of real data. You must use the provided dataset to pass the assignment.

Grade Level: ❌ Fail (Did not analyze the required data)
