      Merry Christmas and Happy new year. Let’s see if some of us can come up any though of your concerns.

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

   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)?

   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

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