Introduction: Mark Weisbrot points me to this report trashing a recent OAS report on Haiti’s elections. Weisbrot writes: The two simplest things that are wrong with the OAS analysis are: (1) By looking only at a sample of the tally sheets and not using any statistical test, they have no idea how many other tally sheets would also be thrown out by the same criteria that they used, and how that would change the result and (2) The missing/quarantined tally sheets are much greater in number than the ones that they threw out; our analysis indicates that if these votes had been counted, the result would go the other way. I have not had a chance to take a look at this myself but I’m posting it here so that experts on election irregularities can see this and give their judgments. P.S. Weisbrot updates: We [Weisbrot et al.] published our actual paper on the OAS Mission’s Report today. The press release is here and gives a very good summary of the major problems with the OAS Mission rep

4 0.057403263 728 andrew gelman stats-2011-05-24-A (not quite) grand unified theory of plagiarism, as applied to the Wegman case

Introduction: A common reason for plagiarism is laziness: you want credit for doing something but you don’t really feel like doing it–maybe you’d rather go fishing, or bowling, or blogging, or whatever, so you just steal it, or you hire someone to steal it for you. Interestingly enough, we see that in many defenses of plagiarism allegations. A common response is: I was sloppy in dealing with my notes, or I let my research assistant (who, incidentally, wasn’t credited in the final version) copy things for me and the research assistant got sloppy. The common theme: The person wanted the credit without doing the work. As I wrote last year, I like to think that directness and openness is a virtue in scientific writing. For example, clearly citing the works we draw from, even when such citing of secondary sources might make us appear less erudite. But I can see how some scholars might feel a pressure to cover their traces. Wegman Which brings us to Ed Wegman, whose defense of plagiari

Introduction: The traditional system of scientific and scholarly publishing is breaking down in two different directions. On one hand, we are moving away from relying on a small set of journals as gatekeepers: the number of papers and research projects is increasing, the number of publication outlets is increasing, and important manuscripts are being posted on SSRN, Arxiv, and other nonrefereed sites. At the same time, many researchers are worried about the profusion of published claims that turn out to not replicate or in plain language, to be false. This concern is not new–some prominent discussions include Rosenthal (1979), Ioannidis (2005), and Vul et al. (2009)–but there is a growing sense that the scientific signal is being swamped by noise. I recently had the opportunity to comment in the journal Political Analysis on two papers, one by Humphreys, Sierra, and Windt, and one by Monogan, on the preregistration of studies and mock reports. Here’s the issue of the journal. Given the hi

2 0.70934892 406 andrew gelman stats-2010-11-10-Translating into Votes: The Electoral Impact of Spanish-Language Ballots

Introduction: Dan Hopkins sends along this article : [Hopkins] uses regression discontinuity design to estimate the turnout and election impacts of Spanish-language assistance provided under Section 203 of the Voting Rights Act. Analyses of two different data sets – the Latino National Survey and California 1998 primary election returns – show that Spanish-language assistance increased turnout for citizens who speak little English. The California results also demonstrate that election procedures an influence outcomes, as support for ending bilingual education dropped markedly in heavily Spanish-speaking neighborhoods with Spanish-language assistance. The California analyses find hints of backlash among non-Hispanic white precincts, but not with the same size or certainty. Small changes in election procedures can influence who votes as well as what wins. Beyond the direct relevance of these results, I find this paper interesting as an example of research that is fundamentally quantitative. Th

Introduction: A correspondent writes: Since you have commented on scientific fraud a lot. I wanted to give you an update on the Diederik Stapel case. I’d rather not see my name on the blog if you would elaborate on this any further. It is long but worth the read I guess. I’ll first give you the horrible details which will fill you with a mixture of horror and stupefied amazement at Stapel’s behavior. Then I’ll share Stapel’s abject apology, which might make you feel sorry for the guy. First the amazing story of how he perpetrated the fraud: There has been an interim report delivered to the rector of Tilburg University. Tilburg University is cooperating with the university of Amsterdam and of Groningen in this case. The results are pretty severe, I provide here a quick and literal translation of some comments by the chairman of the investigation committee. This report is publicly available on the university webpage (along with some other things of interest) but in Dutch: What

Introduction: I received a few emails today on bloggable topics. Rather than expanding each response into a full post, I thought I’d just handle them all quickly. 1. Steve Roth asks what I think of this graph : I replied: Interseting but perhaps misleading, as of course any estimate of elasticity of -20 or +5 or whatever is just crap, and so the real question is what is happening in the more reasonable range. 2. One of my General Social Studies colleagues pointed me to this report , writing “FYI – some interesting new results, using the linked GSS-NDI data. I trust this study will raise some heated discussions.” Another colleague wrote, “I’m rather skeptical of the result but at least they spelled GSS right.” The topic is a paper, “Anti-Gay Prejudice and All-Cause Mortality Among Heterosexuals in the United States,” published by Mark Hatzenbuehler, Anna Bellatorre, and Peter Muennig. My reaction: Yes, it seems ludicrous to me. Especially this: The researchers wante

5 0.66151953 2049 andrew gelman stats-2013-10-03-On house arrest for p-hacking

Introduction: People keep pointing me to this excellent news article by David Brown, about a scientist who was convicted of data manipulation: In all, 330 patients were randomly assigned to get either interferon gamma-1b or placebo injections. Disease progression or death occurred in 46 percent of those on the drug and 52 percent of those on placebo. That was not a significant difference, statistically speaking. When only survival was considered, however, the drug looked better: 10 percent of people getting the drug died, compared with 17 percent of those on placebo. However, that difference wasn’t “statistically significant,” either. Specifically, the so-called P value — a mathematical measure of the strength of the evidence that there’s a true difference between a treatment and placebo — was 0.08. . . . Technically, the study was a bust, although the results leaned toward a benefit from interferon gamma-1b. Was there a group of patients in which the results tipped? Harkonen asked the statis

Introduction: “She was forty years old when she died. It is possible that her art might have developed to include a wider area of human experience, just as possible that the chilling climate of the thirties might have withered it altogether. But what she actually wrote was greatly talented. She deserves a place, although obviously not a foremost one, in any literary history of the years between the wars. The last letter she wrote, or rather dictated, to the printer of the Laforgue translations shows the invariable fastidiousness of her talent, a fastidiousness which is often infuriating but just as often impressive, and is in any case rare enough to be worth remembrance: To the Printer of Six Moral Tales This book is to be spelled and its words are to be hyphenated according to the usage of the Concise Oxford Dictionary.

Introduction: 1. We Bayesian statisticians like to say there are three kinds of statisticians: a. Bayesians; b. People who are Bayesians but don’t realize it (that is, they act in coherence with some unstated probability); c. Failed Bayesians (that is, people whose inference could be improved by some attention to coherence). So, if a statistician does great work, we are inclined to claim this person for the Bayesian cause, even if he or she vehemently denies any Bayesian leanings. 2. In his autobiography, Bertrand Russell tells the story of when he went to prison for opposing World War 1: I [Russell] was much cheered on my arrival by the warden at the gate, who had to take particulars about me. He asked my religion, and I replied ‘agnostic.’ He asked how to spell it, and remarked with a sigh: “Well, there are many religions, but I suppose they all worship the same God.” This remark kept me cheerful for about a week. 3.

Introduction: Marty McKee at Wolfram Research appears to have a very very stupid colleague. McKee wrote to Christian Robert: Your article, “Evidence and Evolution: A review”, caught the attention of one of my colleagues, who thought that it could be developed into an interesting Demonstration to add to the Wolfram Demonstrations Project. As Christian points out, adapting his book review into a computer demonstration would be quite a feat! I wonder what McKee’s colleague could be thinking? I recommend that Wolfram fire McKee’s colleague immediately: what an idiot! P.S. I’m not actually sure that McKee was the author of this email; I’m guessing this was the case because this other very similar email was written under his name. P.P.S. To head off the inevitable comments: Yes, yes, I know this is no big deal and I shouldn’t get bent out of shape about it. But . . .
