B usiness Insider links to this blog with a chart depicting the top beer brands by state. I like the quilt-like appearance brought on by using the packaging of different brands. The nine glowing yellow islands sitting in the Atlantic...

As announced earlier, I’ll be putting my Bayesian Data Analysis course on a G+ hangout. It meets each Friday 8h30 Paris time, starting 18 Oct. Just to try things out, I’ll do a mini-hangout tomorrow (Thurs) 8h30. What I’ll do is set up the hangout, then post the url in a new blog post. I’ll […]The post Test run for G+ hangout for my Bayesian Data Analysis class appeared first…

Matteo Barigozzi and Christian Brownlees have a fascinating new paper, "Network Estimation for Time Series" that connects the econometric time series literature and the statistical graphical modeling (network) literature. It's not only useful, but...

Move your data analysis to a computing environment specifically designed for it. Why R and not spreadsheets? Here are three reasons: complexity graphics money Spreadsheets are easily overwhelmed. Very complex things can be done in spreadsheets — it is just that complex spreadsheets are inefficient and dangerous. Graphics should be considered vital when doing anything with […] The post A first step towards R from spreadsheets appeared first on Burns Statistics.

On Kaiser Fung's Junk Charts blog, he showed a bar chart that was "published by Teach for America, touting its diversity." Kaiser objected to the chart because the bar lengths did not accurately depict the proportions of the Teach for America corps members. The chart bothers me for another reason: [...]

Modélisation hiérarchique, pooling partiel et l’interrogation de bases de données virtuelles P.S. Here are the slides. I only got through a few of them. I have to remember that when I speak in another language, I go much slower. The post My ...

I am visiting the Department of Statistics at the University of Washington today and am enjoying their warm hospitality (thanks Emily!). I have a little breathing room now so I thought I would write a quick blog post. Earlier this year, I posted my contribution to the collection celebrating the 50th anniversary of The Committee […]

Today I had a meeting for one of the projects in which I'm involved. This is a big research grant (in which I have a marginal role, to be honest), with the aim of evaluating some occupational therapy for people with dementia and their carers. Noth...

I recently began messing around with d3.js, which is a Javascript library that makes it possible to create lovely visualizations based on data. In fact, D3 stands for Data Driven Documents. More likely than not, many of the cool graphics and interacti...

In the technology world today, one of the common topics of interest is the so-called "war" between Apple and Google (or Android). This war is ostensibly over dominance of the mobile phone industry, where Apple sells the most popular phone … Continue reading →

The Lego Mindstorm kit provides software and hardware to create programmable robots. A very simple first task is figuring out how to make the robot move any given distance. You get to program the number of wheel rotations. The video … Continue reading →

To recap: Matt Buttice and Ben Highton recently published an article where they evaluated multilevel regression and poststratification (MRP) on a bunch of political examples estimating state-level attitudes. My Columbia colleagues Jeff Lax, Justin Phillips, and Yair Ghitza added some discussion, giving a bunch of practical tips and pointing to some problems with Buttice and […]The post Last word on Mister P (for now) appeared first on Statistical Modeling, Causal…

A short while ago, I introduced Larry Cahoon's blog, GoodStatsBadStats. He started the blog almost two years ago after retiring from the US Census Bureau (site offline due to government shutdown), where he spent 29 years working on the statistical design of most of the household surveys conducted by the Bureau. Cahoon received his PhD from Carnegie Mellon University. Cahoon spent the final seven years of his career working on…

The beta distribution is highly flexible distribution and applies to many situations and environments. The beta distribution applies well when there are percentages. The upcoming New Jersey U.S. Senate election on Wednesday fits that criterion quite well. So here I applied the beta distribution to some pre-election polls where the numbers were obtained through the […]

Following up on our discussion the other day, Matt Buttice and Ben Highton write: It was nice to see our article mentioned and discussed by Andrew, Jeff Lax, Justin Phillips, and Yair Ghitza on Andrew’s blog in this post on Wednesday. As noted in the post, we recently published an article in Political Analysis on […]The post More on Mister P and how it does what it does appeared first…
