Chapter 4 of “Introducing Monte Carlo Methods with R” has four typos (so far) in the exercises:

– In Exercise 4.5, the $overline X_k$ should not be in bold fonts (!)

– In Exercise 4.9, I commented too many lines when revising and thus the variance terms vanished. It should read

$mathbb{E} left[exp-X^2|yright] = frac{1}{sqrt{2 pi sigma^2/y}}intexp{-x^2},exp{-(x-mu)^2y/2sigma^2},text{d}x$

$qquad =frac{1}{sqrt{2 sigma^2/y+1}} exp left{ -frac{mu^2}{1+2sigma^2/y}right}$

– In Exercise 4.13, following the removal of one exercise, Exercise 4.2 should read Exercise 4.1

– In Exercise 4.15, $Bin(y)$ should be $Bin(n,y)$ (as in Problem 4.5 of Monte Carlo Statistical Methods)
