Prediction Intervals with Changing Variance

Learning goals

• Load and inspect MODULE8_HOUSING_VARIANCE_SYNTHETIC.
• Run the Python cells connected to Prediction under Heteroskedasticity.
• Interpret the output using heteroskedasticity and robust standard errors.

Common errors

• File not found: check that module8_housing_variance_synthetic.csv is installed or use the course data folder.
• Package import error: use the browser notebook first, then download for local Jupyter if your local packages differ.
• Column name error: compare your variable names with the dataset variables listed for this notebook.
