A very impressive group of people in the equities group created an investment platform that integrates multiple and diverse data sources as well as data visualization tools with a seamless hand-off between research and production.
American Century Investments is a top-20 mutual fund company with more than 125 billion dollars of assets under management. The quantitative investment group manages 22 funds, and takes an objective, systematic and disciplined approach to determine which stocks to buy and sell. Real-time data and carefully calibrated statistical models are the foundation of this quantitative approach. This group formerly had a disparate blend of closed third-part...

A great example of Simpson's Paradox. US wages have declined since 2000 within every educational class (high school dropouts, graduates, etc.). But the headline (overall) rate says that wages have increased since 2000. 
Since 2000, the median US wage has risen about 1%, adjusted for inflation. But over the same period, the median wage for: high school dropouts, high school graduates with no college education, people with some college education, and people with Bachelor’s or higher degrees have all decreased. In other words, within every educational subgroup, the median wage is lower now than it was in 2000. How can both things be true: overall wages have risen, ...

 This 4-hour workshop shows how to perform the most commonly used data management tasks in R. For many topics we will cover both the standard built-in approach and then perform the same task using add-on packages that are often much easier to use. 
We will devote most of our time to working through examples that you may run simultaneously on your computer. However, handouts will include each step and its output if you prefer instead just relax and take notes.  At the end of the workshop, you will receive a set of practice exercises for you to do on your own time, as well as solutions to the problems. The instructor will be available via email to address these problems or any other topic in the workshop.

The Oxford and Cambridge rowing clubs have found a unique method for finding the best crew given a difficult contraint: their rivers aren't wide enough to run traditional races. Instead, boats line up in single file and swap positions when they bump each other. This re-ordering is preserved from race to race and from year to year, making for a bubble-sort simulation that's been running for nearly 200 years. http://blog.revolutionanalytics.com/2013/03/worlds-longest-mcmc.html

Found a great deal on Angie's list, and the guys were there the very next day. Jose and Tai arrived promptly, and had my garage cleaned out in no time. No surprises on the bill either! Great service.
