Introduction: I was reading this article by Ariel Levy in the New Yorker and noticed something suspicious. Levy was writing about an event in 1979 and then continued: One year later, Ronald Reagan won the Presidency, with overwhelming support from evangelicals. The evangelical vote has been a serious consideration in every election since. From Chapter 6 of Red State, Blue State : According to the National Election Study, Reagan did quite a bit worse than Carter among evangelical Protestants than among voters as a whole–no surprise, really, given that Reagan was not particularly religious and Cater was an evangelical himself. It was 1992, not 1980, when evangelicals really started to vote Republican. What’s it all about? I wouldn’t really blame Ariel Levy for this mistake; a glance at her website reveals a lot of experience as a writer and culture reporter but not much on statistics or politics. That’s fine by me: there’s a reason I subscribe to the New Yorker and not

2 0.18241242 551 andrew gelman stats-2011-02-02-Obama and Reagan, sitting in a tree, etc.
Introduction: I saw this picture staring at me from the newsstand the other day: Here’s the accompanying article, by Michael Scherer and Michael Duffy, which echoes some of the points I made a few months ago , following the midterm election: Why didn’t Obama do a better job of leveling with the American people? In his first months in office, why didn’t he anticipate the example of the incoming British government and warn people of economic blood, sweat, and tears? Why did his economic team release overly-optimistic graphs such as shown here? Wouldn’t it have been better to have set low expectations and then exceed them, rather than the reverse? I don’t know, but here’s my theory. When Obama came into office, I imagine one of his major goals was to avoid repeating the experiences of Bill Clinton and Jimmy Carter in their first two years. Clinton, you may recall, was elected with less then 50% of the vote, was never given the respect of a “mandate” by congressional Republicans, wasted

Introduction: An interview with me from 2012 : You’re a statistician and wrote a book, Red State, Blue State, Rich State, Poor State , looking at why Americans vote the way they do. In an election year I think it would be a good time to revisit that question, not just for people in the US, but anyone around the world who wants to understand the realities – rather than the stereotypes – of how Americans vote. I regret the title I gave my book. I was too greedy. I wanted it to be an airport bestseller because I figured there were millions of people who are interested in politics and some subset of them are always looking at the statistics. It’s got a very grabby title and as a result people underestimated the content. They thought it was a popularisation of my work, or, at best, an expansion of an article we’d written. But it had tons of original material. If I’d given it a more serious, political science-y title, then all sorts of people would have wanted to read it, because they would
Introduction: Stephen Olivier points me to this horrible, horrible news article by Jonathan Haidt, “Why working-class people vote conservative”: Across the world, blue-collar voters ally themselves with the political right . . . Why on Earth would a working-class person ever vote for a conservative candidate? This question has obsessed the American left since Ronald Reagan first captured the votes of so many union members, farmers, urban Catholics and other relatively powerless people – the so-called “Reagan Democrats”. . . . Sorry, but no no no no no. Where to start? Here’s the difference between upper-income and lower-income votes in presidential elections: Ronald Reagan did about 20 percentage points better among voters in the upper third of income, compared to voters in the lower third. The relation between income and voting since 1980 is about the same as it was in the 1940s. Oh yeah, Haidt said something about “across the world.” How bout this: It varies. In mos
5 0.13761777 394 andrew gelman stats-2010-11-05-2010: What happened?
Introduction: A lot of people are asking, How could the voters have swung so much in two years? And, why didn’t Obama give Americans a better sense of his long-term economic plan in 2009, back when he still had a political mandate? As an academic statistician and political scientist, I have no insight into the administration’s internal deliberations, but I have some thoughts based on my interpretation of political science research. The baseline As Doug Hibbs and others have pointed out, given the Democrats’ existing large majority in both houses of Congress and the continuing economic depression, we’d expect a big Republican swing in the vote. And this has been echoed for a long time in the polls–as early as September, 2009–over a year before the election–political scientists were forecasting that the Democrats were going to lose big in the midterms. (The polls have made it clear that most voters do not believe the Republican Party has the answer either. But, as I’ve emphasized before

Favorite character types include jocks, movie stars, folksy Texans and war heroes. . . . [But the frontrunners for the 2012 Republican nomination] make Michael Dukakis look like John F. Kennedy.

Introduction: Last month we reported on some claims of irregularities in the recent Russian elections. Just as a reminder, here are a couple graphs: Yesterday someone pointed me to two online articles: Mathematical proof of fraud in Russian elections unsound and US elections are as ‘non-normal’ as Russian elections . I know nothing about Russian elections and will defer to the author and his commenters on the details. That said, I don’t find the arguments to be at all persuasive. The protesters show drastic differences between the patterns of votes of Putin’s party and the others, and the linked articles seem a bit too eager to debunk. I wouldn’t necessarily blog on this but I was unhappy to see this material on the website of Significance, which is an official publication of the American Statistical Association and the Royal Statistical Society. The quality control at this site seems low. I clicked through the links and found this : Barring the revelation of a hoax

Fourth Annual Bayesian Biostatistics Conference Including the star of that recent Cochrane TV debate who will be the key note speaker.

Introduction: Joe Blitzstein and Xiao-Li Meng write : An effectively designed examination process goes far beyond revealing students’ knowledge or skills. It also serves as a great teaching and learning tool, incentivizing the students to think more deeply and to connect the dots at a higher level. This extends throughout the entire process: pre-exam preparation, the exam itself, and the post-exam period (the aftermath or, more appropriately, afterstat of the exam). As in the publication process, the first submission is essential but still just one piece in the dialogue. Viewing the entire exam process as an extended dialogue between students and faculty, we discuss ideas for making this dialogue induce more inspiration than perspiration, and thereby making it a memorable deep-learning triumph rather than a wish-to-forget test-taking trauma. We illustrate such a dialogue through a recently introduced course in the Harvard Statistics Department, Stat 399: Problem Solving in Statistics, and tw
4 0.88101935 203 andrew gelman stats-2010-08-12-John McPhee, the Anti-Malcolm
Introduction: This blog is threatening to turn into Statistical Modeling, Causal Inference, Social Science, and Literature Criticism, but I’m just going to go with the conversational flow, so here’s another post about an essayist. I’m not a big fan of Janet Malcolm’s essays — and I don’t mean I don’t like her attitude or her pro-murderer attitude, I mean I don’t like them all that much as writing. They’re fine, I read them, they don’t bore me, but I certainly don’t think she’s “our” best essayist. But that’s not a debate I want to have right now, and if I did I’m quite sure most of you wouldn’t want to read it anyway. So instead, I’ll just say something about John McPhee. As all right-thinking people agree, in McPhee’s long career he has written two kinds of books: good, short books, and bad, long books. (He has also written many New Yorker essays, and perhaps other essays for other magazines too; most of these are good, although I haven’t seen any really good recent work from him, and so
5 0.87108761 1513 andrew gelman stats-2012-09-27-Estimating seasonality with a data set that’s just 52 weeks long
Introduction: Kaiser asks: Trying to figure out what are some keywords to research for this problem I’m trying to solve. I need to estimate seasonality but without historical data. What I have are multiple time series of correlated metrics (think department store sales, movie receipts, etc.) but all of them for 52 weeks only. I’m thinking that if these metrics are all subject to some underlying seasonality, I should be able to estimate that without needing prior years data. My reply: Can I blog this and see if the hive mind responds? I’m not an expert on this one. My first thought is to fit an additive model including date effects, with some sort of spline on the date effects along with day-of-week effects, idiosyncratic date effects (July 4th, Christmas, etc.), and possible interactions. Actually, I’d love to fit something like that in Stan, just to see how it turns out. It could be a tangled mess but it could end up working really well!
