Paul Alper writes: Maybe it is time to return to really important things such as medical swindles in particular, Tamiflu. Consider Tamifu and its financially-influenced and influential supportors as seen from the fabulous Susan Perry of Minnpost: The group of researchers who conducted the Lancet study [supporting Tamiflu]was described in a commentary that accompanied their […] The post You won’t believe this story: Tamiflu conflict of interest appeared first on…

Imagine White-style robust OLS inference, but with robustness to endogeneity as opposed to heteroskedasticity/autocorrelation (or maybe even robustness to all three). It sounds too good to be true. Actually, it sounds impossible, and even i...

Nadia Hassan writes: Earlier you had waxed nostalgic for the days when people sent you bad graphs. This [from Javier Zarracina] is not a stand-out on that front, but it is far from ideal: A lot of buzz in recent years about data journalism or quantitative journalism.

Here they are: What to think about in 2015: How can the principles of statistical quality control be applied to statistics education Stethoscope as weapon of mass distraction “Why continue to teach and use hypothesis testing?” Relaxed plagiarism standards as a way to keep the tuition dollars flowing from foreign students What to do in […] The post Top posts of 2015 appeared first on Statistical Modeling, Causal Inference, and…

Bayesian data analysis is cool, Markov chain Monte Carlo is the cool technique that makes Bayesian data analysis possible, and wouldn’t it be coolness if you could do all of this in the browser? That was what I thought, at least, and I’ve now made bayes.js: A small JavaScript library that implements an adaptive MCMC sampler and a couple of probability distributions, and that makes it relatively easy to implement…

Paul Alper points us to this in-depth article by Steven Brill on the topic of Alex Gorsky, the pharma executive who notoriously marketed a dangerous drug and hid the evidence of its dangers.

The story is fascinating from a statistical perspective but it has no chess […] The post Definitely got nothing to do with chess IV appeared first on Statistical…

I've been working on a Shiny app and wanted to display some math equations. It's possible to use LaTeX to show math using MathJax, as shown in this example from the makers of Shiny. However, by default, MathJax does not allow in-line equations, because the dollar sign is used so frequently. But I needed to use in-line math in my application. Fortunately, the folks who make MathJax show how to…

From the Stan users list: I have just started to look into the output of the optimizing function and it seems to give estimates slightly different than the ones that I had previously obtained through maximum likelihood estimation (using MATLAB). Can you please tell me what is the penatly that the LBFGS algorithm imposes? In […] The post Showdown in Vegas: When the numbers differ in the third decimal place…
