Strengths: A clearly written project which identifies and tests a hypothesis of practical interest.

Points for consideration:

  1. Histogram of data is generally less informative than histogram of detrended data or residuals: it is the last of these for which normality helps model specification.

  2. Typos:

    • \(\epsilon\in\) should be \(\epsilon\sim\)
    • \(\psi_p\) should be \(\psi_q\).

  3. Develop math notation rather than writing \(xreg_2\).

  4. Missing statement on contributions within the group, requested in the project description.
