Another review of Introducing … R

May 2, 2011 | xi'an

The March 2011 issue of JASA contains a review of Introducing Monte Carlo Methods with R by Hedibert Lopes. As in the previous review, the poor quality of the figures is (rightly) pointed out by Hedie. However, the main message of the review remains very positive and, furthermore, Hedie advertises the ‘...

R-ecap [-16]

March 26, 2011 | xi'an

This morning, I noticed that none of my R related posts had appeared on R-bloggers for the past fortnight… After investigating, this was caused by…cut-and-paste! Indeed, when advertising about the special issue of TOMACS Arnaud Doucet and I edit about Monte Carlo methods in Statistics, I copied the main ... [Read more...]

Typos sorted, at last!

March 23, 2011 | xi'an

After posting so many entries about typos in my books (making you wonder how there could be any text left!) and postponing their classification for so long, I decided on Saturday afternoon to collect those entries into a comprehensive pdf document that should be more useful for readers. I incidentally ... [Read more...]

cut&paste typo in R book

March 2, 2011 | xi'an

A casualty of cut-and-paste in Chapter 3 of Introducing Monte Carlo Methods with R. Brad McNeney from Simon Fraser sent me a nice email about the end of Example 3.6 missing a marginal estimate. Indeed, it does. And it should have been obvious from the “estimates” we derived, 19 and 16, which are not ... [Read more...]

Introducing Monte Carlo Methods with R [precision]

January 17, 2011 | xi'an

Doug Rivers, professor of Political Sciences in Stanford, kindly sent me this email yesterday night: The 2nd displayed equation in section 2.1.2 on p. 44 is garbled (it might be interpreted as saying that U and X have the same distribution). I think you intended: And indeed we should have stated the ...

Missing reference in Monte Carlo Statistical Methods

January 15, 2011 | xi'an

A few days ago, Peng Yu sent me this email Dear Prof. Robert, The citation Edwards and Sokal (1988) appears on page 326 of your book MCSM2. However, I don’t find in in the Reference section (it would have appear on page 601 if it is in the reference section). I don’...

More typos in Chapter 5

December 29, 2010 | xi'an

Following Ashley’s latest comments on Chapter 5 of Introducing Monte Carlo Methods with R, I realised Example 5.5 was totally off-the-mark! Not only the representation of the likelihood should have used prod instead of mean, not only the constant should call the val argument of integrate, not only integrate  uses lower ...

Typo in Example 5.18

October 2, 2010 | xi'an

Edward Kao pointed out several typos in Example 5.18 of Monte Carlo Statistical Methods. First, the customers in area i should be double-indexed, i.e. which implies in turn that . Then the summary T should be defined as and as given that the first m customers have the fifth plan missing. ...

Typo in Bayesian Core [again]

May 15, 2010 | xi'an

Reza Seirafi from Virginia Tech sent me the following email about Bayesian Core, which alas is pointing out a real typo in the reversible jump acceptance probability for the mixture model: With respect to the expression provided on page 178 for the acceptance probability of the split move, I was wondering ...

An obscure integral

April 7, 2010 | xi'an

Here is an email from Thomas I received yesterday about a computation in our book Introducing Monte Carlo Methods with R: I’m currently reading your book “Introduction to Monte Carlo Methods with R” and I quite highly appreciate your work. I’m not able to see how the integral ... [Read more...]

Joining R-bloggers

February 18, 2010 | xi'an

Upon request by the blog administrator, Tal Galili, I have joined R-bloggers, which aggregate blog entries about R into a central place. I feel I have much more to learn than to teach about R (as can be seen from earlier comments on my R programs in Introducing Monte Carlo ... [Read more...]

Typos in Chapters 1, 4 & 8

February 10, 2010 | xi'an

Thomas Clerc from Fribourg pointed out an embarassing typo in Chapter 8 of “Introducing Monte Carlo Methods with R”, namely that I defined on page 247 the complex number as the squared root of 1 and not of -1! Not that this impacts much on the remainder of the book but still an ... [Read more...]

Typos in Chapter 8

January 16, 2010 | xi'an

Phew!, we are now done with the solution manual in the sense that we have compiled solutions for all odd-numberedd exercises (but one!) and solved a fair number of even-numbered exercises. As it stands, the manual is 120 pages long and I am exhausted by the run to produce it over ...

Typos in Chapters 6-7

January 14, 2010 | xi'an

Over the weekend and during the R exams, I managed to complete the solution set for Chapters 6 and 7 of “Introducing Monte Carlo Methods with R”. Chapter 6 only exhibited a few typos, despite me covering most exercises in Chapter 6, hence the merging of both chapters. – in Exercise 6.13, both and [...]

Typos in Chapter 5

January 11, 2010 | xi'an

After writing the solutions to the odd-numbered exercises in Chapter 5 of “Introducing Monte Carlo Methods with R”., I alas found the following typos, two of which are rather major (Exercise 5.3 and Example 5.16). I apologise to the readers these typos may confuse. – Exercise 5.3 has no simple encompassing set and the constraint ...

Typos in Chapter 4

January 9, 2010 | xi'an

Chapter 4 of “Introducing Monte Carlo Methods with R” has four typos (so far) in the exercises: – In Exercise 4.5, the 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 – In Exercise 4.13, following the removal of [...]

Typos in Chapter 3

January 7, 2010 | xi'an

Here are two more typos in the exercises of Chapter 3 of “Introducing Monte Carlo Methods with R”. – due to the (later) inclusion of an extra-exercise in the book, the “above exercise” in Exercise 3.5 actually means Exercise 3.3. – in Exercise 3.11, question c, a line got commented by mistake in the LaTeX file ...

Typos in Chapter 2

January 5, 2010 | xi'an

When grading homeworks for my Monte Carlo graduate class, I found that my students had pointed out two typos in the exercises of Chapter 2 of “Introducing Monte Carlo Methods with R”. – In Exercise 2.17, question d. should be “d. Show that the maximum of is attained at .“ – In Exercise 2.21, in item [...]
