The area of bibliometrics is not my area of expertise but is still of interest as a researcher. I sometimes think about how Google has impacted the way we title articles. Gone are the days of witty, snappy titles. Title … Continue reading →

Following up on our recent post, I clicked on some of Ziliak’s links and found lots of good stuff, especially the post by Berk Ozler. I have no knowledge of his work but I like his writing; see here, for example. Ziliak replied: Ozler’s post is very good indeed, and well written. Ozler’s suggestion for […] The post More on those randomistas appeared first on Statistical Modeling, Causal Inference, and…

This is part 3 of my response to Gelman's post about the DST/heart attacks study. The previous parts are here and here. One of the keys of vetting any Big Data/OCCAM study is taking note of the decisions made by the researchers in conducting the analysis. Most of these decisions involve subjective adjustments or unverifiable assumptions. Not that either of those things are inherently bad - indeed, any analysis one…

A workshop on statistics and neuroscience, to take place at the University of Warwick, UK, Sept. 3-5 2014. We’ll talk spikes, voxels, pixels, MCMC, and so on.Official call for posters below the fold. We are pleased to announce that a workshop on “Statistical Challenges in Neuroscience” will take place Sept. 3 to 5, 2014 in […]

In my book Simulating Data with SAS, I show how to use the SAS DATA step to simulate data from a logistic regression model. Recently there have been discussions on the SAS/IML Support Community about simulating logistic data by using the SAS/IML language. This article describes how to efficiently simulate […]

After more than a year of collaboration, meetings, simulations, delays, switches, visits, more delays, more simulations, discussions, and a final marathon wrapping day last Friday, Jean-Michel Marin, Pierre Pudlo, and I at last completed our latest collaboration on ABC, with the central arguments that (a) using random forests is a good tool for choosing the […]

Yup, another social psychology researcher from northwestern Europe who got results that people just don’t believe. I’m a fan of Retraction Watch but not a regular reader so I actually heard about this one indirectly, via this email from Baruch Eitam which contained the above link and the following note: Of the latest troubles in […] The post Too Linear To Be True: The curious case of Jens Forster appeared…

I was reading one of my favorite stats blogs, StatsChat, where Thomas points to this article in the Atlantic and highlights this quote: Dassault Systèmes is focusing on that level of granularity now, trying to simulate propagation of cholesterol in human … Continue reading →

Steve Ziliak wrote in: I thought you might be interested in the following exchanges on randomized trials: Here are a few exchanges on the economics and ethics of randomized controlled trials, reacting to my [Zilliak's] study with Edward R. Teather-Posadas, “The Unprincipled Randomization Principle in Economics and Medicine”. Our study is forthcoming in the Oxford […] The post Smullyan and the Randomistas appeared first on Statistical Modeling, Causal Inference, and…

Cox’s Theorem implies that we either use Bayes or our methods will violate some simple but desirable properties. This has two consequences: (1) Frequentist methods such as p-values, which aren’t equivalent to posteriors, are guaranteed to b...
