Extreme Right Bibliography Online

Over the last two decades I have accumulated thousands of references that have travelled with me all the way from bibtex-mode through Endnote, Citavi and some more obscure packages until we finally came full circle and ended up in bibtex-mode again. To my mild surprise, my use of (some) keywords has been fairly consistent so that it was relatively easy (using make, bibtool and bibtex2html) to create a 380+ entries strong online bibliography on the Extreme Right in Western Europe. Enjoy.

All singing, all dancing 3d function plots with beamer, pgfplots and animate.sty

Source: Long/Freese, Regression Models for Categorical Dependent Variables Using Stata

I use emacs/ $\LaTeX$ for all my textprocessing needs, and for the last four or five years, I have created all my slides with Till Tantaus excellent “beamer” class. At the moment, I’m teaching a 2nd year stats course (imagine doing this with PowerPoint – the horror! the horror!), so I sometimes use graphs from the assigned text like this one from Long&Freese that illustrates the latent variable/threshold interpretation of the binary logit model. The message should be fairly clear: $y^{*}$ depends on $x$ andfollows a standard logistic distribution around its conditional mean.

How to get from Stata to Pajek

I’m teaching an introductory SNA class this year. Following a time-honoured tradition, I conducted a small network survey at the beginning of the class using Limesurvey. Getting the data from Limesurvey to Stata via CSV was easy enough. Here is the data set. But how does one get the data from Stata to Pajek for analysis? Actually, it’s quite easy.

First, we need to change the layout of the data. In the data set, there is one record for each of the 13 respondent. Each record has 13 variables, one for each (potential) arc connecting the respondent to other students in the class. This is equivalent to Stata’s “wide” form. Stata’s reshape command will happily re-arrange the data to the “long” form, with one record for each arc. This is what Pajek requires.

Statistics and Data links roundup for November 23rd through December 29th

Statistics and Data links roundup for November 23rd through December 29th:

The Data and Story Library – DASL (pronounced “dazzle”) is an online library of datafiles and stories that illustrate the use of basic statistics methods. We hope to provide data from a wide variety of topics so that statistics teachers can find real-world examples that will be interesting to their students. Use DASL’s powerful search engine to locate the story or datafile of interest.

Radicalism and Fluffy Bunnies

Without doubt, late December is exactly the right time for reflection and (re-)assessment. Looking back on the last months, I had too many conference dinners, not nearly enough conference beers/chats, and definitively too many conference papers to read. Amongst these, the prize for the most original political science graph (along with the price for the most pointless use of too-cute images) goes to the unnamed creator of the pastiche on the right, which I have not made up and which probably just goes to show that concepts of the good are relative. Or something along these lines. As an aside, I am sure that somewhere in the world there is a culture for which The Fluffy Bunny is evil incarnate.
