What the Take-Home tests

Regression theory is the single most concrete piece of Aquatic-specific intel we have, so make it the priority.

How to prepare for the Take-Home

  • Own OLS end to end — the normal equations, when (XᵀX)⁻¹ exists, Gauss–Markov, omitted-variable bias, and what R² does and does not tell you.
  • Be ready for regularization — ridge / lasso trade-offs and why you would reach for either on noisy financial data.
  • Show research hygiene in the write-up — Aquatic lists it first among behavioural requirements. State assumptions, show your validation, and say what would falsify your result.
