Back to the Future? Using 'big data' to bet on sport

It may sound like a gambler's dream but a team of statisticians are working on ways to beat the bookies by predicting sporting events.

The mathematicians at Cardiff University use "big data" collected from thousands of previous sports results to analyse odds and to make bets.

So could big data help create a guide to coming sports events similar to the almanac featured in the Back to the Future films?

Prof Anatoly Zhigljavsky explained the idea behind the research.
