## Real Pirate Attacks, Charted with R

September 19, 2013
By

To mark Talk Like a Pirate Day, Bob Rudis uses R to animate a map of the cumulative real-world pirate attacks since 1978: Looks like the Carribean and the West Indes, traditional pirate haunts, are still active. But the real hot-spot in modern times is Africa. Find the R code behind the animation at the blog post linked below....

Avast me hearRties! (ok, enough of the pirate speak in a blog post) It wouldn’t be TLAPD without out some modest code & idea pilfering from Mark Bulling & Simon Raper. While those mateys did a fine job hoisting up some R code (your really didn’t think I’d stop with the pirate speak, did you?)

## An animated peek into the workings of Bayesian Statistics

September 9, 2013
By

One of the practical challenges of Bayesian statistics is being able to deal with all of the complex probability distributions involved. You begin with the likelihood function of interest, but once you combine it with the prior distributions of all the parameters, you end up with a complex posterior distribution that you need to characterize. Since you usually can't...

One of the approaches to graph drawing is application of so called force-directed algorithms. In its simplest form the idea is to layout the nodes on plane so that all edges in the graph have approximately equal length. This problem has very intuitive ...

The slides for my ECVP tutorial on classification images are available here. Try this alternative version if the equations look funny. (image from Mineault et al. 2009) The slides are in HTML and contain some interactive elements. They’re the result of experimenting with R Markdown, D3 and pandoc. You write the slides in R Markdown,

With the FMS Symphony by csv soundsystem you can listen to the Global Financial Crisis as you watch interest rates plunge while the Treasury floods the market with emergency funds. The source data for the chart and music comes from daily emails (like this one) sent by the US Treasury summarizing the cash spending and borrowing of the Federal...

## Warrior Zombies from Outer Space II: Mayhem Unleashed

August 20, 2013
By

Given the speed at which I consume them, it's only justified that the first post on this blog is about movies. (Although, by that logic, it could have equally well been about sandwiches, Nutella, or tissue paper. Note to self: Look for a Nutella consumption dataset) Anyway, this post is about movie taglines - specifically, the words that...

A very busy spring has transitioned into a very busy summer, so let me recap a few topics that probably deserve more time than I’ll give them here. Here are the things I’m overdue on, in no particular order: Publications In the March edition of the Journal of Risk, Kris Boudt, Brian Peterson and I
