My daughter returned home from college a few weeks ago. She's a business major and just completed a challenging semester that included classes in statistics, accounting and finance. Of the three, she professed to finding finance the most interesting. In the stocks and bonds portion of the finance class, the professor spent quite a bit of time teaching from the acclaimed book “ A Random Walk Down Wall Street: The Time-Tested Strategy for Successful Investing ” by Princeton academic, Burton Malkiel. RWDWS's...Read more

Six months ago I purchased a subscription to the New York Times Digital, which provides access to the online newspaper and for my iPad. I like it a lot, experiencing much less paper withdrawal than anticipated and no doubt now spending more time reading articles than before. A collateral benefit to being part of the “Times ecosystem” is exposure to other solid news sources. One illustration is the new policy and politics website, The Upshot , that was launched several months ago by more

It just had to be serendipity. Early one morning several weeks ago, I had two emails awaiting me -- one from the Wire headlining an article on the results of analyses of Medicare data that the government's made available to the public; and a second from analytics vendor WPL announcing version 3.1 of its statistical software WPS that “can run programs written in the language of SAS.” That email also directed me to update my demo license and install 3.1. I spent parts of twenty years programming with SAS,...Read more

What an exciting tournament! If you’re an NCAA hoops junkie like me, you enjoyed the past 3 weeks of action. From the upsets (Mercer over Duke…seriously, Mercer?) to Cinderella stories (Go Dayton Flyers!) to buzzer beaters and clutch shots (Kentucky’s Aaron Harrison against Louisville, Michigan and Wisconsin. That’s simply insane!) , there is no better time of year to gather with family and friends and immerse yourself in the annual basketball festival that is the NCAA tournament. You have to give second...Read more

I just finished Tom Davenport's latest book, “ Big Data @ Work ” and, not surprisingly, liked it a lot. Indeed I've pretty much enjoyed everything I've read by the author . A Harvard-trained sociologist, Davenport is a methodologically-sound researcher. His deep interviews and surveys of executives and data scientists set a standard for excellence in an industry where marketing bravado generally supersedes scientific rigor. And though Davenport's writing is often not as provocative, as, say, that of Viktor...Read more

If you're lucky, you work for a company that gives you FREE MONEY if you're a responsible adult and ferret away retirement money in a 401K or Simple IRA plan. A hundred times I've heard the phrase, "Always take the free money," but is that always the right choice? How do you know if you're really getting a good deal? My girlfriend (for privacy's sake we'll call her 'Penelope Portman') was struggling with that decision last weekend and asked me to review her 401k pamphlet. She has her choice of 35 different...Read more

One of the big changes in OpenBI's business over our eight years of BI and analytics consulting has been the evolution of “reporting”. In 2006, print-like reports were the norm, with OLAP and visualization secondary. Now OLAP and graphical dashboards predominate. Indeed, many customers have pretty much abandoned traditional “pixel-perfect”, control breaks reporting for visual drill/slice-and-dice, dashboards and statistical graphs. Figure 1 (click to enlarge) Nobody's happier about that development than me...Read more

The brackets are set. Let the madness begin! In Part 1 of this series, I introduced two methods for ranking NCAA teams: a Linear Algebra approach based on a lecture given by Tim Chartier at the Museum of Mathematic,s and a PageRank approach which I applied by reframing the entire NCAA season as a directed, weighted graph. In this blog, we'll compare these ratings approaches with the established industry rating systems of RPI , BPI , Ken Pomeroy and Jeff Sagarin . We'll make use of R's statistical...Read more
