Summary

Enhances the student loan repayment validation notebook with deeper analysis and documentation of known limitations.

Changes

  • Add correlation analysis among those required to pay (weighted correlation: 0.68)
  • Document why overall correlation is low (33% of reporters have income below threshold)
  • Add deep dive on zero modelled repayments cases
  • Document known limitations:
    • No cap at outstanding balance
    • FRS data issues (voluntary payments, intra-year income variation)
  • Add calibration status section noting WAS imputation opportunity
  • Fix enum handling for StudentLoanPlan string values
  • Clarify that FRS student_loans variable is THIS YEAR borrowing, not outstanding balance

Test plan

  • Notebook runs without errors
  • Analysis is consistent with previous findings
