## Sunday data/statistics link roundup (10/6/2013)

A fascinating read about applying decision theory to mathematical proofs. They talk about Type I and Type II errors and everything.  Statistical concepts explained through dance. Even for a pretty culture-deficient dude like me this is cool. Lots of good … Continue reading →

The past one has been a very interesting week, which I've spent visiting the University of Las Palmas, in the Canary Island. Since it was the last week on maternity leave for Marta, we all went. I knew the weather would be good, but we didn't expect it...

## Ideas that spread fast and slow

October 6, 2013
By

Atul Gawande (the thinking man’s Malcolm Gladwell) asks: Why do some innovations spread so swiftly and others so slowly? Consider the very different trajectories of surgical anesthesia and antiseptics, both of which were discovered in the nineteenth century. The first public demonstration of anesthesia was in 1846. The Boston surgeon Henry Jacob Bigelow was approached […]The post Ideas that spread fast and slow appeared first on Statistical Modeling, Causal Inference,…

## Influence Analysis for Repeated Measures Data

October 6, 2013
By

I am trying exercise 59.8 (page 5057) of the SAS/STAT Users Guide 12.3 in R. The interesting thing is that influence is investigated on subject level rather than individual level. The diagnostics in nlme does not do leave-subject-out, at least, not tha...

## Was Janina Hosiasson pulling Harold Jeffreys’ leg?

October 6, 2013
By

The very fact that Jerzy Neyman considers she might have been playing a “mischievous joke” on Harold Jeffreys (concerning probability) is enough to intrigue and impress me (with Hosiasson!). I’ve long been curious about what really happened. Eleonore Stump, a leading medieval philosopher and friend (and one-time colleague), and I pledged to travel to Vilnius […]

## Estimating rates from a single occurrence of a rare event

October 5, 2013
By

Elon Musk’s writing about a Tesla battery fire reminded me of some of the math related to trying to estimate the rate of a rare event from a single occurrence of the event (plus many non-event occurrences). In this article we work through some of the ideas. Elon Musk wrote that the issues of the […] Related posts: Sample size and power for rare events What is a large enough…

## Give me a ticket for an aeroplane

October 5, 2013

How long are songs? Gabriel Rossman discusses the two peaks, one at just under 3 minutes and one at just under 4 minutes. He quotes musician Jacob Slichter: In anticipation of “crossing over” the single to radio formats . . . Each mix had to be edited down to under four minutes, an important limit […]The post Give me a ticket for an aeroplane appeared first on Statistical Modeling, Causal…

## A functional Gibbs sampler in Scala

October 4, 2013
By

For many years I’ve had a passing interest in functional programming and languages which support functional programming approaches. I’m also quite interested in MOOCs and their future role in higher education. So I recently signed up for my first on-line course, Functional Programming Principles in Scala, via Coursera. I’m around half way through the course […]

Editor's note: Simply Statistics is still freaking out about the government shut down and potential impending economic catastrophe if the debt ceiling isn't raised. Since anything new we might write seems trivial compared to what is going on in Washington, … Continue reading →

I am familiar with the U.S. Federal Reserve System. Long ago I spent the first three (wonderful) years of my working life as an economist at the Board of Governors in DC, 1986-1989. Most recently I chaired the Fed's Model Validation Council, 2012-2013....

## Financial Data Accessible from R

October 4, 2013
By

This post lists the sources and types of financial data that is accessible directly from R. I included here free and non free ressources. Obviously given the size and the activity of the R community this is work in constant progress. I might update this survey in the future. Any comments welcome.

## Discussion with Dan Kahan on political polarization, partisan information processing. And, more generally, the role of theory in empirical social science

October 4, 2013
By

It all began with this message from Dan Kahan, a law professor who does psychology experiments: My graphs– what do you think?? I guess what do you think of the result too, but the answer is, “That’s obvious!”  If it hadn’t been, then it would have been suspicious in my book. Of course, if we […]The post Discussion with Dan Kahan on political polarization, partisan information processing. And, more generally,…

## Scientific communication that accords you “the basic human dignity of allowing you to draw your own conclusions”

October 4, 2013
By

Amanda Martinez, a writer for The Atlantic and others, advised attendees that her favorite writing “accorded me the basic human dignity of allowing me to draw my own conclusions.” I really like that way of putting it, and this is something we tried hard to do with Red State Blue State, to put the information […]The post Scientific communication that accords you “the basic human dignity of allowing you to…

## Questions on my online forecasting course

October 4, 2013
By

I’ve been getting emails asking questions about my upcoming course on Forecasting using R. Here are some answers. Do I need to use the Revolution Enterprise version of R, or can I use open-source R? Open source R is fine. Revolution Analytics is organizing the course, but there is no requirement to use their software. I will be using open source R with Rstudio for demonstrating things in lectures. Is…

People keep pointing me to this excellent news article by David Brown, about a scientist who was convicted of data manipulation: In all, 330 patients were randomly assigned to get either interferon gamma-1b or placebo injections. Disease progression or death occurred in 46 percent of those on the drug and 52 percent of those on […]The post On house arrest for p-hacking appeared first on Statistical Modeling, Causal Inference, and…
