The Use of Sampling Weights in Bayesian Hierarchical Models for Small Area Estimation

December 19, 2014
By

All this discussion of plagiarism is leaving a bad taste in my mouth (or, I guess I should say, a bad feeling in my fingers, given that I’m expressing all this on the keyboard) so I wanted to close off the workweek with something more interesting. I happened to come across the above-titled paper by […] The post The Use of Sampling Weights in Bayesian Hierarchical Models for Small Area…

Defense by escalation

December 19, 2014
By

Basbøll has another post regarding some copying-without-attribution by the somewhat-famous academic entertainer Slavoj Zizek. In his post, Basbøll links to theologian and professor Adam Kotsko (cool: who knew there were still theologians out and about in academia?) who defends Zizek, in part on the grounds that Zizek’s critics were being too harsh. Kotsko writes of […] The post Defense by escalation appeared first on Statistical Modeling, Causal Inference, and Social…

Message to Booleans: It’s an additive world, we just live in it

December 18, 2014
By

Boolean models (“it’s either A or (B and C)”) seem to be the natural way that we think, but additive models (“10 points if you have A, 3 points if you have B, 2 points if you have C”) seem to describe reality better—at least, the aspects of reality that I study in my research. […] The post Message to Booleans: It’s an additive world, we just live in it…

I’d like to see a preregistered replication on this one

December 17, 2014
By

Under the heading, “Results too good to be true,” Lee Sechrest points me to this discussion by “Neuroskeptic” of a discussion by psychology researcher Greg Francis of a published (and publicized) claim by biologists Brian Dias and Kerry Ressler that “Parental olfactory experience [in mice] influences behavior and neural structure in subsequent generations.” That’s a […] The post I’d like to see a preregistered replication on this one appeared first…

Expectation propagation as a way of life

Aki Vehtari, Pasi Jylänki, Christian Robert, Nicolas Chopin, John Cunningham, and I write: We revisit expectation propagation (EP) as a prototype for scalable algorithms that partition big datasets into many parts and analyze each part in parallel to perform inference of shared parameters. The algorithm should be particularly efficient for hierarchical models, for which the […] The post Expectation propagation as a way of life appeared first on Statistical Modeling,…

Damn, I was off by a factor of 2!

I hate when that happens. Demography is tricky. Oh well, as they say in astronomy, who cares, it was less than an order of magnitude! The post Damn, I was off by a factor of 2! appeared first on Statistical Modeling, Causal Inference, and Social Scien...

“Now the company appears to have screwed up badly, and they’ve done it in pretty much exactly the way you would expect a company to screw up when it doesn’t drill down into the data.”

December 15, 2014

Palko tells a good story: One of the accepted truths of the Netflix narrative is that CEO Reed Hastings is obsessed with data and everything the company does is data driven . . . Of course, all 21st century corporations are relatively data-driven. The fact that Netflix has large data sets on customer behavior does […] The post “Now the company appears to have screwed up badly, and they’ve done…
