  1. And I have one more:
    If you got to vote, would you prefer the name Bootstrap method or the name Shotgun method? (p.25)

  2. Here’s my first question:
    Would you say that there is any contradiction between “We have applied the bootstrap in a nonparametric way…”(p.25) and the discussion about the need to centralize the residuals so that \( \sum_{i=1}^n \epsilon_i=0 \) (p.17-19)?

  3. Notes on using LaTeX

    You can use standard LaTeX commands to display mathematical formulas.

    If you type

    Given that \( \boldsymbol{Y} = \boldsymbol{X}\beta + \epsilon \) 
    where \(\epsilon \sim N(\mu,\sigma^2)\)

    will give you

    Given that \( \boldsymbol{Y} = X\beta + \epsilon \) where \(\epsilon \sim N(\mu,\sigma^2)\).

    Also if you type

    \[
    \left( \sum_{k=1}^n a_k b_k \right)^{\!\!2} \leq
     \left( \sum_{k=1}^n a_k^2 \right) \left( \sum_{k=1}^n b_k^2 \right)
    \]

    will give you

    \[\left( \sum_{k=1}^n a_k b_k \right)^{\!\!2} \leq
    \left( \sum_{k=1}^n a_k^2 \right) \left( \sum_{k=1}^n b_k^2 \right)
    \].
