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... [Read more...]

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.

Previously, I did a simple Bayesian projection of recent temperature using proxy data and the methods shown in McShane and Wyner (2010).

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 ... [Read more...]

For the last two cycles I’ve done some simple regression analysis of the informal vote.  I saw Possum have his go at it, using a specification that is virtually the same as what I’ve run in the past (2007, 2004).

I wrote a short talk demonstrating the use the R package {estout} for tonight’s New England R Users Group meeting.  NB this is not a discussion of the econometric model, but rather a demonstration of how to get publication-quality results out of R efficiently. The basic functions of {estout} ... [Read more...]

In an earlier post, I discussed how to use Subversion to download, edit, and generate a patch against R‘s source code. Since most of us can’t commit our code changes back to R‘s repository, we can consider alternatives to store and maintain our patch, until it is ... [Read more...]
