Fantasy Sports Betting: The Next 'Big Thing' Thanks to Big Data

Many believe that Fantasy Sports Betting (FSB) is the next immensely popular online game, similar to the arrival of Poker a decade ago, and the incredible growth of the industry in the USA is the best proof of that.

Big Data, a promised land where the Big Bucks grow

Consider this: Many people come up to me in the street, and, apropos of nothing, they ask me how they can make money from Big Data.

Addition of Different Dimensions to Data

I was often the lone wolf among my peers in university because I supported a prominent place in society for corporations and an important social role for capital. I questioned whether the directors and executives of companies entered into boardrooms really intending to “oppress” people such as minorities and people with disabilities. Did they deliberately make bathrooms inaccessible to people in wheelchairs perhaps to advance their preconceptions of who gets to go to the bathroom, I pondered…

Estimating Operational Risk Capital: the Challenges of Truncation, the Hazards of MLE, and the Promise of Robust Statistics

J.D. Opdyke and Alex Cavallo

In operational risk measurement, the estimation of severity distribution parameters is the main driver of capital estimates, yet this remains a non-trivial challenge for many reasons.  Maximum likelihood estimation (MLE) does not adequately meet this challenge because of its well-documented non-robustness to modest violations of idealized textbook model assumptions, specifically that the data are independent and identically distributed (i.i.d.), which is…
