Analyze all your comparisons. That’s better than looking at the max difference and trying to do a multiple comparisons correction.

Analyze all your comparisons.  That’s better than looking at the max difference and trying to do a multiple comparisons correction.

[cat picture] The following email came in: I’m in a PhD program (poli sci) with a heavy emphasis on methods. One thing that my statistics courses emphasize, but that doesn’t get much attention in my poli sci courses, is the problem of simultaneous inferences. This strikes me as a problem. I am a bit unclear […] The post Analyze all your comparisons. That’s better than looking at the max difference…

Not everyone’s aware of falsificationist Bayes

June 20, 2017
By

Stephen Martin writes: Daniel Lakens recently blogged about philosophies of science and how they relate to statistical philosophies. I thought it may be of interest to you. In particular, this statement: From a scientific realism perspective, Bayes Factors or Bayesian posteriors do not provide an answer to the main question of interest, which is the […] The post Not everyone’s aware of falsificationist Bayes appeared first on Statistical Modeling, Causal…

Alex Konkel writes: I was a little surprised that your blog post with the three smaller studies versus one larger study question received so many comments, and also that so many people seemed to come down on the side of three smaller studies. I understand that Stephen’s framing led to some confusion as well as […] The post Breaking the dataset into little pieces and putting it back together again…

Homecoming (of sort…)

I spent last week in Florence for our Summer School. Of course, it was home-coming for me and I really enjoyed being back to Florence $-$ although it was really hot. I would say I'm not used to that level of heat anymore, if it wasn't for the fact that...

Don’t say “improper prior.” Say “non-generative model.”

June 18, 2017
By

[cat picture] In Bayesian Data Analysis, we write, “In general, we call a prior density p(θ) proper if it does not depend on data and integrates to 1.” This was a step forward from the usual understanding which is that a prior density is improper if an infinite integral. But I’m not so thrilled with […] The post Don’t say “improper prior.” Say “non-generative model.” appeared first on Statistical Modeling,…

Joachim Krueger writes: As many of us rely (in part) on p values when trying to make sense of the data, I am sending a link to a paper Patrick Heck and I published in Frontiers in Psychology. The goal of this work is not to fan the flames of the already overheated debate, but […] The post Ride a Crooked Mile appeared first on Statistical Modeling, Causal Inference, and…

Statistical Challenges of Survey Sampling and Big Data Andrew Gelman, Department of Statistics and Department of Political Science, Columbia University, New York Big Data need Big Model. Big Data are typically convenience samples, not random samples; observational comparisons, not controlled experiments; available data, not measurements designed for a particular study. As a result, it is […] The post Statistical Challenges of Survey Sampling and Big Data (my remote talk in…

So: for once I woke up this morning feeling slightly quite tired for the late night, but also rather upbeat after an election. The final results of the general election are out and have produced quite some shock. Throughout yesterday, it look...
