Introduction: You know that expression, “Not from the Onion”? How did we say that, all those years before the Onion existed? I was thinking about this after encountering (amidst a Google search for something else) this article on a website called “College News”: DANVILLE, KY., March 8, 2007–Two Centre College professors spent the past six years reading and analyzing 200 children’s books to discover a disturbing trend: gender bias still exists in much of modern children’s literature. Dr. David Anderson, professor of economics, and Dr. Mykol Hamilton, professor of psychology, have documented that gender bias is common today in many children’s books in their research published recently in Sex Roles: A Journal of Research titled “Gender Stereotyping and Under-Representation of Female Characters in 200 Popular Children’s Picture Books: A 21st Century Update.” . . . “Centre College,” huh? That’s where Area Man is studying, right? According to the materials on its website, Centre College is

Introduction: Ramu Sudhagoni writes: I am working on combining three longitudinal studies using Bayesian hierarchical technique. In each study, I have at least 70 subjects follow up on 5 different visit months. My model consists of 10 different covariates including longitudinal and cross-sectional effects. Mixed models are used to fit the three studies individually using Bayesian approach and I noticed that few covariates were significant. When I combined using three level hierarchical approach, all the covariates became non-significant at the population level, and large estimates were found for variance parameters at the population level. I am struggling to understand why I am getting large variances at population level and wider credible intervals. I assumed non-informative normal priors for all my cross sectional and longitudinal effects, and non-informative inverse-gamma priors for variance parameters. I followed the approach explained by Inoue et al. (Title: Combining Longitudinal Studie

Introduction: 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 will be part of a larger program aimed at developing and applying methods for network analysis in psychology and psychopathology (see a recent review on the topic: Borsboom & Cramer, 2013). The specific research topic will depend on the expertise and interest of the candidate, but will involve one or more of the following: Statistical methods for high dimensional data, multilevel modeling, or nonlinear dynamical models. Interested candidates are encouraged to contact Francis Tuerlinckx (francis.tuerlinckx@ppw.kuleuven.be) and Denny Borsboom (dennyborsboom@gmail.com) for more information.

Introduction: Neil Malhotra writes: I just wanted to alert to this completely misinformed Politico article by Roger Simon, equating sampling theory with “magic.” Normally, I wouldn’t send you this, but I sent him a helpful email and he was a complete jerk about it. Wow—this is really bad. It’s so bad I refuse to link to it. I don’t know who this dude is, but it’s pitiful. Andy Rooney could do better. And I don’t mean Andy Rooney in his prime, I mean Andy Rooney right now. The piece appears to be an attempt at jocularity, but it’s about 10 million times worse than whatever the worst thing is that Dave Barry has ever written. My question to Neil Malhotra is . . . what made you click on this in the first place? P.S. John Sides piles on with some Gallup quotes.

5 0.88000059 314 andrew gelman stats-2010-10-03-Disconnect between drug and medical device approval
Introduction: Sanjay Kaul wrotes: By statute (“the least burdensome” pathway), the approval standard for devices by the US FDA is lower than for drugs. Before a new drug can be marketed, the sponsor must show “substantial evidence of effectiveness” as based on two or more well-controlled clinical studies (which literally means 2 trials, each with a p value of <0.05, or 1 large trial with a robust p value <0.00125). In contrast, the sponsor of a new device, especially those that are designated as high-risk (Class III) device, need only demonstrate "substantial equivalence" to an FDA-approved device via the 510(k) exemption or a "reasonable assurance of safety and effectiveness", evaluated through a pre-market approval and typically based on a single study. What does “reasonable assurance” or “substantial equivalence” imply to you as a Bayesian? These are obviously qualitative constructs, but if one were to quantify them, how would you go about addressing it? The regulatory definitions for
