Borel Dice Edition - Brute Forcing Experiments

 

Borel and Borel: Dice Edition are educational games about probability. I picked up a copy of each because I thought they would be useful in introducing some ideas of probability and gambling without the cultural baggage of better known games.

 

I'm biased because it's my field, but Borel has a lot more play value than most games of its kind. The dice edition, which is much easier to find, and easier to get into and play, has a set of 7 dice (four 6-sided, and one each of a 10-sided, 20-sided and 30-sided die), and a deck of 100 "experiments", like Experiment 001:

T1B: Goodhart's Law and Baserunning

When I was about 11 years old, I was good at running, good enough to represent my elementary school as the anchor in a relay at a district track meet. This prompted all the grown-ups in my life to coach me on running. They told me all sorts of tricks about keeping my hands flat and remembering to breathe and to keep in a straight line and to keep from dragging my feet and to start early to get the baton.

The race came and I did all those things – hands, breathing, straight line, no dragging, start early. I forgot, however, to run. I blew a huge lead by running in perfect form, but in slow motion.

What's the lesson here?

Lost Chapter: Writing for your Career

 This is one of the 'lost chapters' of the textbook "Writing for Statistics and Data Science", which was removed because information changes too quickly. This chapter covers data science resumes, describing class projects to businesses, and writing letters of introduction to potential grad supervisors.

Review of The Theory of Gambling and Statistical Logic

 

There are two reasons why I read Review of The Theory of Gambling and Statistical Logic, Second Edition (2009), by Richard A. Epstein, which dictated which of the text's 440 pages I paid attention to and which I skimmed.

 

First, to learn more of the fundamentals of betting strategy for my current job at Sportlogiq. Second, to get material to include in a possible future Statistics and Gambling course.

Fantasy League Sports Cards

 

The sports card industry (specifically baseball cards) crashed in 1994. Fantasy sports existed as early as the 60's, but really caught public attention around 1995. That timing is not coincident.

In both hobbies, fans get to have  surrogate ownership of players, and the market value of those surrogates goes up or down with the performance of those players. At the casual level, being in a fantasy league is just a more publicly acceptable way to collect and play with cards. At the serious level, fantasy is a more viable, faster way to make a profit with your expertise than cards were.

In short, fantasy is just trading cards for grown ups.

But what if physical cards let you draft players?

Soccer-to-Hockey Translation Guide

Hockey and soccer (ice hockey and football) are similar enough from a fan or analytics perspective that if you’re familiar with one, it’s easy to become familiar with another. There could be a whole new world of sport you’re missing out on!

In this article I’ve organized many of the parallels and contrasts between hockey and soccer so that you can watch a few games and of either one and confidently say that "hockey is just like soccer except X instead of Y".
