2013 : Understanding the Tipsters, Margin Predictors and Fund Algorithms

Compared to most previous seasons, the number of changes to MAFL Funds and algorithms this year has been very small. Consequently, this post from last year remains a good source of general information about how MAFL works. 

The only information I'd add by way of update would be that:

• Many algorithms now use a slightly different version of Implicit Bookmaker Probabilities. The differences between the Implicit Probabilities we'll use now and those we'd use previously given the same market prices are always small, but using the new version of the probabilities does seem to generally improve the predictive powers of the algorithms.
• There are some changes to the MAFL Funds and their underlying algorithms and wagering strategies, which you can read about in this blog. Probably the greatest change is that all Funds will now wager all season long.

For those of you who would like to know even more about the algorithms used in MAFL, I've also created a downloadable PDF with details of each algorithm's inputs, outputs, type/method of creation and purpose, as well as, in some cases, the actual equations themselves. MAFL is nothing if not transparent.
