### The St. Petersburg paradox

http://en.wikipedia.org/wiki/St._Petersburg_paradox

In economics, theSt. Petersburg paradoxis a paradox related to probability theory and decision theory. It is based on a particular (theoretical) lottery game (sometimes calledSt. Petersburg Lottery) that leads to a random variable with infinite expected value, i.e., infinite expected payoff, but would nevertheless be considered to be worth only a very small amount of money. The St. Petersburg paradox is a classical situation where a naïve decision criterion (which takes only the expected value into account) would recommend a course of action that no (real) rational person would be willing to take. Several resolutions are possible.

### Investing: Kelly Criterion

Over the last few years - while researching trading strategies - I happened to learn about the Kelly Criterion:

http://en.wikipedia.org/wiki/Kelly_criterion

In probability theory, theKelly criterion, orKelly strategyorKelly formula, orKelly bet, is a formula used to determine the optimal size of a series of bets. In most gambling scenarios, and some investing scenarios under some simplifying assumptions, the Kelly strategy will do better than any essentially different strategy in the long run. It was described by J. L. Kelly, Jr in 1956

### Library Additions: Gambling and Mathematics

I'm interested in learning more about the fine art of becoming a better player of various games of chance (in particular, those that are popular in Las Vegas), and developing a better edge in the management of my own personal portfolio trading strategies.

I believe that developing skills in the former will aide me in my goals for the latter.

And so, I've been slowly amassing a small library of books on various topics related to gambling skills, and some directly (or indirectly) related to the mathematics of such games.

The Mathematics of Blackjack

### Why One Statistician Buys Lottery Tickets

David Wood's discussion of the probabilities of buying lottery tickets is an entertaining read:

http://simplexify.net/blog/2012/5/6/i-am-a-statistician-and-i-buy-lottery-tickets.html

"The decision of whether to buy a lottery ticket shouldn’t be based on the probability of winning, or the expected return of a ticket, but on the entertainment value that comes from imagining a different life. If that entertainment value compares favourably with other activities with a similar price, then go for it. Plus, it has the added bonus that you might actually win; one-in-a-million events happen every day. Someone eventually wins the big prize, and you have to be in to win" - David Woods

### Julia Language

Here's an interesting language for mathematical endeavors

From the Julia blog:

Julia is a dynamic language in the tradition of Lisp, Perl, Python and Ruby. It aims to advance expressiveness and convenience for scientific and technical computing beyond that of environments like Matlab and NumPy, while simultaneously closing the performance gap with compiled languages like C, C++, Fortran and Java.

Most high-performance dynamic language implementations have taken an existing interpreted language and worked to accelerate its execution. In creating Julia, we have reconsidered the basic language design, taking into account the capabilities of modern JIT compilers and the specific needs of technical computing. Our design includes:

Julia feels light and natural for data exploration and algorithm prototyping, but has performance that lets you deploy your prototypes.

- Multiple dispatch as the core language paradigm.
- Exposing a sophisticated type system including parametric dependent types.
- Dynamic type inference to generate fast code from programs with no declarations.
- Aggressive specialization of generated code for types encountered at run-time.
