Integrating collection, analysis, and interpretation of data in social and behavioral research Andrew Gelman, Department of Statistics and Department of Political Science, Columbia University The replication crisis has made us increasingly aware of the flaws of conventional statistical reasoning based on hypothesis testing. The problem is not just a technical issue with p-values, not can […]
Fred Buchanan, a student at Saint Anselm’s Abbey School, writes: I’m writing a paper on the influence of Jorge Luis Borges in academia, in particular his work “The Garden of Forking Paths”. I noticed that a large number of papers from a wide array of academic fields include references to this work. Your paper, “The […]

StanCon 2018 Helsinki talk slides, notebooks and code have been sometime available in StanCon talks repository, but it seems we forgot to announce this. The StanCon 2018 Helsinki talk list includes also links to videos. StanCon’s version of conference proceedings is a collection of contributed talks based on interactive notebooks. Every submission is peer reviewed […]
Jerrod Anderson points us to Table 1 of this paper: It seems that the null hypothesis that this particular group of men and this particular group of women are random samples from the same population, is false. Good to know. For a moment there I was worried. On the plus side, as Anderson notes, the […]

3.2 N-P Tests: An Episode in Anglo-Polish Collaboration* We proceed by setting up a specific hypothesis to test, H0 in Neyman’s and my terminology, the null hypothesis in R. A. Fisher’s . . . in choosing the test, we take into account alternatives to H0 which we believe possible or at any rate consider it most important to be […]
Here are some thoughts from the noted biologist and writer, collected by Lior Pachter.
I’d seen a few of these Watson quotes before, but it’s kinda stunning to see them all in one place. Apparently he recommends never adopting an Irish kid…
Excursion 3 Statistical Tests and Scientific Inference Tour I Ingenious and Severe Tests [T]he impressive thing about [the 1919 tests of Einstein’s theory of gravity] is the risk involved in a prediction of this kind. If observation shows that the predicted effect is definitely absent, then the theory is simply refuted.The theory is incompatible with […]
It’s easy to laugh at Stephen Wolfram, and I don’t like some of his business practices, but he’s an excellent writer and is full of interesting ideas. This long introduction to neural network prediction algorithms is an example. I have no idea if Wolfram wrote this book chapter himself or if he hired one of […]

Last year we discussed the story of an article, “Variation in the β-endorphin, oxytocin, and dopamine receptor genes is associated with different dimensions of human sociality,” published in PNAS that, notoriously, misidentified what a peptide was, among other problems. Recently I learned of a letter published in PNAS by Patrick Jern, Karin Verweij, Fiona Barlow, […]
Mark White writes: I have a question regarding using multilevel models for multiple comparisons, per your 2012 paper and many blog posts. I am in a situation where I do randomized experiments, and I have a lot of additional demographic information about people, as well. For the moment, let us just assume that all of […]
