  • 70 Years of Analytics: Evaluating the Job Performance of Presidents

    Tuesday, November 17, 2015 - 17:00
    The October 2015 employment figures were recently released, and the 271,000 new jobs added with a 5.0% unemployment rate were cause for celebration for those of blue persuasion, while yet more consternation for those of the red.

  • Baseball Analytics Proves a Theory

    Wednesday, November 11, 2015 - 10:00
    After years of playing fantasy basketball, I realized that drafting strategies and the discussion surrounding them havent changed much. Whats been lacking is a mathematical discussion of these drafting strategies. For example, the statement assists are rare is generally accepted as truth without assessing to what extent it is true.

    With another successful Labor Day camping trip behind us, we’ve only got a few trips left before we pack it in for 2015. On this most recent trip, we wanted to find some fresh, local Sweet Corn for the evening meal. Finding a local Farmer’s Market or Produce stand near the campground is way better than hauling it in.
