The Chicago Symphony hosted the world premiere of Louis last evening, and I had snatched the (literally) last available ticket. The film, which is written, directed and producted by Dan Pritzker, is based loosely on the early years of Louis Armstro...

We’re starting to get more divisions reporting two-candidate preferred numbers by vote type. The emerging picture (literally) is one in which Labor’s performance on the pre-polls and postals is lagging its performance in ordinary votes. On the other hand, Labor seems to be doing well among absentee voters (the regression line sitting above the 45

Previously, I did a simple Bayesian projection of recent temperature using proxy data and the methods shown in McShane and Wyner (2010). I showed that when you take out the last 30 years of data (1969~1998), the projection does not track the recent uptick in temperatures well. The “projection” is a simple unparametric bootstrap which

As announced on the R-Sig-Finance mailing list, the University of Washington is now offering a three-course online certificate in computational finance, using the R programming language as the software base. The three courses are: Investment Science R Computing for Computational Finance Portfolio Construction and Risk Management The course is presented by Doug Martin (founder of S-PLUS and longtime computational...

Although I use Excel all the time, and I strongly encourage my students to use it for performance analysis and CaP, I was forced to include a warranty disclaimer in my GCaP book because I discovered a serious numerical error while writing Appendix B. There, my intention was just to show that Excel gives essentially the same results...

Thanks to everyone who attended our webinar this morning, Big Data Analysis for R Using Revolution R Enterprise, and in particular thanks for all the thoughtful questions during the Q&A session. If you missed the live broadcast, a replay is now available (requires the ability to view WMV files), and you can also download the slides in PDF format....

In an effort to achieve this (last paragraph), I created a couple of functions to coerce networks as ‘igraph’ objects to networks as ‘network’ objects and vice versa. I wrapped them into a package called ‘intergraph’ which I just uploaded to my personal miniCRAN. Please mind, this is still an experimental version! Might be bug-infested.

Just joined R bloggers (https://www.r-bloggers.com/). I'm using R to write G-code for the milling maching. This evening (10/25/2010), I'll give a talk on this at the DC-area UseR meetup. Here's a link to the presentation: http://files.meetup.com/1503...
