Why are trolls so bothersome?

We don’t get a lot of trolls on this blog. When people try, I typically respond with some mixture of directness and firmness, and the trolls either give up or perhaps they recognize that I am answering questions in sincerity, which does not serve their trollish purposes. But I’m pretty sure that my feeling is […] The post Why are trolls so bothersome? appeared first on Statistical Modeling, Causal Inference,…

The PACE trial and the problems with discrete, yes/no thinking

I don’t often read the Iranian Journal of Cancer Prevention, but I like this quote: I was thinking more about the PACE trial. God is in every leaf of every tree. There’s been a lot of discussion about statistical problems with the PACE papers, and also about the research team’s depressing refusal to share their […] The post The PACE trial and the problems with discrete, yes/no thinking appeared first…

Hierarchical modeling when you have only 2 groups: I still think it’s a good idea, you just need an informative prior on the group-level variation

Judea Pearl and I briefly discuss extrapolation, causal inference, and hierarchical modeling

December 5, 2015
By

OK, I guess it looks like the Buzzfeed-style headlines are officially over. Anyway, Judea Pearl writes: I missed the discussion you had here about Econometrics: Instrument locally, extrapolate globally, which also touched on my work with Elias Bareinboim. So, please allow me to start a new discussion about extrapolation and external validity. First, two recent […] The post Judea Pearl and I briefly discuss extrapolation, causal inference, and hierarchical modeling…

Mindset interventions are a scalable treatment for academic underachievement — or not?

October 7, 2015
By

Someone points me to this post by Scott Alexander, criticizing the work of psychology researcher Carol Dweck. Alexander looks carefully at an article, “Mindset Interventions Are A Scalable Treatment For Academic Underachievement,” by David Paunesku, Gregory Walton, Carissa Romero, Eric Smith, David Yeager, and Carol Dweck, and he finds the following: Among ordinary students, the […] The post Mindset interventions are a scalable treatment for academic underachievement — or not?…

Have weak data. But need to make decision. What to do?

September 21, 2015
By

Vlad Malik writes: I just re-read your article “Of Beauty, Sex and Power”. In my line of work (online analytics), low power is a recurring, existential problem. Do we act on this data or not? If not, why are we even in this business? That’s our daily struggle. Low power seems to create a sort […] The post Have weak data. But need to make decision. What to do? appeared…

Comments on Imbens and Rubin causal inference book

September 7, 2015
By

Guido Imbens and Don Rubin recently came out with a book on causal inference. The book’s great (of course I would say that, as I’ve collaborated with both authors) and it’s so popular that I keep having to get new copies because people keep borrowing my copy and not returning it. Imbens and Rubin come […] The post Comments on Imbens and Rubin causal inference book appeared first on Statistical…
