Issue in eq 36.45-36.47

In eq 36.45:

• It seems odd to me we're using Q-hat but not g-hat. Mistake?
• Y is missing the subscript i
• Since this is an estimator, shouldn't it be P-hat and not P?

In eq 36.46:

• similar comments to 36.45
  • On LHS, we use Q, g and on the RHS, we use Q-hat.

In eq 36.47:

• Shouldn't there be a "^2"? Since it's a variance
