At the upcoming 2012 summer meeting of the Society of Political Methodology, I will be presenting a poster on Isarithmic Maps of Public Opinion. Since last posting on the topic, I have made major improvements to the code and robustness of the modeling approach, and written a tutorial that illustrates the production of such maps.
This tutorial is in a very rough draft form, but I will post it here when it is finalized. (An earlier draft had some errors, and so I have taken it down.)
