## New typos in Monte Carlo Statistical Methods

Three weeks ago, I got this email from Amir Alipour, an Iranian student, about typos in Monte Carlo Statistical Method:

“I found some typos in the book which were not reported at your website. I list them blow, I would appreciate if you let me know if I`m right.
1.       Page 4, line 9,  $(\theta_1,\ldots,\theta_n,p_1,\ldots,p_n)$, the index should not be $k$ instead of $n$?
2.       Page 4, example 1.3, last line, $n>q$, should be $n>=q$ (as we have $x_0$ ).
3.       Page 5, the likelihood of MA(q), it seems $\sigma^{-(n+q)}$ should  change to  $\sigma^{-(n+q+1)}$.
4.       Page 8, formula (1.10).  The gradient symbol $\nabla$ is used for the first time without introducing, while it is used for the second time on page 19 with introducing.
5.       Page 8, Example 1.6, the log part in $\psi(\theta)$, should  change to $\log(-1/(2\theta_2))$.
6.       Page 10, in modified Bessel function, $z$ should change to $t$.
7.       Page 10, Example 1.9, in the likelihood function, the power of $\sigma$ should be $-n$, and the power of the function under product should be $-\frac{p+1}{2}$. (Even Figure 1.1 is not consistent with likelihood)”

and I have posted those new typos on the associated webpage. Amir Alipour has thus managed to find seven yet undiscovered typos in the first ten pages of the book! I am quite grateful to Amir Alipour for signaling those typos. Especially the final one which is due to an intented presentation of the $t$ density as a polynomial, with a poor wording: the likelihood of a $t$ sample is proportional to a power of a polynomial in the location parameter. (And there still is a typo since $\sigma^{n(p+1)/2}$ should be $\sigma^{2n/(p+1)}$…) Now I can only hope Amir Alipour can proceed through the whole book with the same amount of dedication!
