The KDD Cup is an annual competition to build the best predictive model from a large data set. This years' contest tasked entrants to predict the likelihood of a student dropping out from one of XuetangX's massively-online open courses, based on the student's prior activities. The competition closed on July 12, and yesterday, the winning teams were announced.

If R had a theme song, maybe this would be it. (With thanks to Ben Sayre.)

June was a hot month for extreme statistics and R. Not only did we close out the month with useR! 2015, but two small conferences in the middle of the month brought experts together from all over the world to discuss two very difficult areas of statistics that generate quite a bit of R code.

In my previous post on The network structure of CRAN I demonstrated how to use page rank and communities to visualize the structure of a graph.

At UseR!2015 I discussed my work with Gabor Csardi, the maintainer of the igraph package.  Gabor gave me lots of helpful advice.

Creating an email course for my R packages has significantly increased the number of people who use the packages. It has also reduced the learning curve for the packages and brought me into greater contact with my users. In this post I will share the 5 steps I took to create my course Learn to Map Census Data in R.

EMC recently ran a competion to find out why John McGuinness, the legendary motorcycle racer known as the "Morecambe Missile", is outperforms the average motorcycle racer. To answer this question, EMC instrumented his bike and his suit with a number of real-time sensors. (Data collected included gear and RPM for the bike, and heart rate and acceleration for the rider.) They did the same for Adam Child, a motorcycle racing journalist who acted as a "control" in this study.

In just four days, the New Horizons probe will finally reach (and fly by) Pluto, and for the first time in more than 25 years give us detailed images of a brand new planet. (Well, dwarf planet.) I've been excited about this mission for years, and can't wait to see what's out there.
