$Two textbooks on probability using R$

This fall, I’ll be teaching a second-year course on Probability with Computer Applications, which is required for Computer Science majors.  I’ve taught this before, but that was five years ago, so I’ve been looking to see what new textbooks would be suitable.  The course aims not just to use computer science applications as examples, but

## solaR 0.24 at CRAN

The version 0.24 of solaR is at CRAN and R-Forge. Some days before the 0.23 version was uploaded, but I had to make a quick fix to readMAPA: the url of http://www.mapa.es/siar has been changed to http://www.marm.es/siar. Moreover, this function has been renamed to readSIAR, although it is still available as readMAPA. Consequently the mode

## Further Bernoulli factories

Yesterday, Andrew Thomas and José Blanchet posted a note on the Bernouilli factory on arXiv. This short paper links with the recent paper of Flegal and Herbei I commented earlier. Considering the special target Thomas and Blanchet develop an elaborate scheme of cascading envelopes that converge to f from above. Their paper is very clear

An earlier post (1216) introduced a compatibility study (i.e. reverse engineering) of the sas7bdat database file format. The code and documentation for this are here: http://github.com/biostatmatt/sas7bdat. I've recently restructured the code as an R package, and added some functionality. Look for the sas7bdat package on the CRAN. Also, the read.sas7bdat code has been ported to

## Sweave source for poll report

Sweave source for the poll report for those who expressed some interest. You’ll also need this file of R function definitions, utilities.R. I also wrote a little shell script that calls Sweave and xelatex etc, hacking the Sweave.sh script that ships with R.

Earlier, I looked at the HadCRUT3vgl data set using generalized least squares to investigate whether the trend in temperature since 1995 was statistically significant. Here I want to follow-up one of the points from the earlier posting; namely using a … Continue reading →

## Rotating disks

My neighbour is an half-retired entrepreneur who still runs his electric engine company. A few weekends ago, he came to me with the following physics question related with one of those engines: given a primary disk rotating at the angular speed of ω0 and a secondary disk located on the first one with a centre

## Australians and Americans, 10 years after 9/11

With Lynn Vavreck at UCLA, I ran parallel public opinion surveys in Australia and the United States, measuring attitudes on security, the fight against terrorism, the wars in Afghanistan etc, some 10 years after the 9/11 attacks. Full report here (gene...

## An Application of boot() to IV regression

Bootstrapping standard errors can be a useful technique when obtaining closed form for the standard error formula is difficult or intractable. In this post, I give an example of how to use R to create a bootstrap sampling distribution in the context o...
