Labor vote share across different types of balloting

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

Excel Errors and Other Numerical Nightmares

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...

August 24, 2010

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). The 2010 edition follows.  As usual, electorate-level informality in House of Reps voting increases with

Demonstration of {estout}

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} are modeled on the Stata package estout.

In a two-part series at the Los Angeles R User Group, Ryan Rosario took a look at the many ways you can take the R language to the limits of high-performance computing. In Part I (see video at this link; slides and code also available), Ryan focuses on the various methods of parallel computing in R. There's some great...

Get Everything Set Up I’m going to assume that you have access to a machine that will run JAGS. If you don’t, then you should be able to use WinBUGS, which is very easy to get set up. Unfortunately, the details of what follows may not help you as much if you’re using WinBUGS. To

I found time and read Gelman and Hill’s “Data Analysis Using Regression and Multilevel / Hierarchical Models“…Now, please do yourself a favour and get it (of course the paperback version ). Even for experienced or intermediate (myself) this will be a treat for your eyes and neurons. PS : (Confession) I didn’t like the Bayesian ...read more
