Somebody emailed me: I am a researcher at ** University and I have recently read your article on average predictive comparisons for statistical models published 2007 in the journal “Sociological Methodology”. Gelman, Andrew/Iain Pardoe. 2007. “Average Predictive Comparisons for Models with Nonlinearity, Interactions, and Variance Components”. Sociological Methodology 37: 23-51. Currently I am working with […]
Francis Tuerlinckx announces that he and Denny Borsboom have a joint postdoctoral position. It sounds really cool: The position is in the Research Group of Quantitative Psychology and Individual Differences at the University of Leuven (Belgium) and involves frequent travel to and contact with the Psychological Methods group in Amsterdam. The research of the postdoc […]
OK, fine. Maybe they could work Stan on to the show next? I thought I could retire once I’d successfully inserted the phrase “multilevel regression and poststratification” into the NYT, but now I want more more more. Maybe a cage match between Stan and Mister P on the Itchy and Scratchy show?
Devin Caughey points out a typo in the second column of page 765 of our AJPS paper. Here’s what we have: The typo is in the third line of the second paragraph above. Where it says y^*_j = y.bar^*_j n_j, it should be y^*_j = y.bar^*_j n^*_j. One frustrating system of the current system of […]
The above graph shows the estimated support, by state, for the Employment Nondiscrimination Act, a gay rights bill that the Senate will be voting on this Monday. The estimates were constructed by Kate Krimmel, Jeff Lax, and Justin Phillips using multilevel regression and poststratification. Check out that graph again. The scale goes from 20% to […]
I received the following email from someone who wishes to remain anonymous: My colleague and I are trying to understand the best way to approach a problem involving measuring a group of individuals’ abilities across time, and are hoping you can offer some guidance. We are trying to analyze the combined effect of two distinct […]
Ben Highton and Matt Buttice point us to this response addressing some of the issues Jeff Lax raised in his most recent MRP post. P.S. Jeff replies in comments: It sounds like we’ve converged. They acknowledge MRP performance is significantly better on average than reported in their new paper in PA and yet performance variation […]
The following should be catnip for Andrew. It combines (a) statistics on baby names, (b) time series, and (c) statistics broken down by state. All in one really fun animated visualization by Reuben Fischer-Baum: Sixty Years of the Most Popular Names for Girls As Mark Liberman commented in his re-post on Language Log, this data […]
Modélisation hiérarchique, pooling partiel et l’interrogation de bases de données virtuelles P.S. Here are the slides. I only got through a few of them. I have to remember that when I speak in another language, I go much slower.
To recap: Matt Buttice and Ben Highton recently published an article where they evaluated multilevel regression and poststratification (MRP) on a bunch of political examples estimating state-level attitudes. My Columbia colleagues Jeff Lax, Justin Phillips, and Yair Ghitza added some discussion, giving a bunch of practical tips and pointing to some problems with Buttice and […]
