paparainbow Posted February 28, 2014 Share Posted February 28, 2014 Hi, should someone build an algorithm that calculates odds for rugby (lets say union), what would be the best way to approach it? Do you think that pythagorean expectation is a good approach. I use it, but I have a significant deviation from bookies in my odds. Is there any distribution method u think that would give a better approach. The scoring system may be the reason I default, that the minimum score is 3 and not 1, like in football,basketball, handball and other time based sports.

Marazan Posted March 1, 2014 Share Posted March 1, 2014 Re: rugby in play algorithm for odds compiling I have noticed (or at least back in 2011 when I did some data collection on it) that there tends to be an over-reaction to tries being scored in close games, the market will shorten "too far" and then bounce back a few hundreths at least all within a minute or so. Someone with a High Speed trading algo and a good model of price-over-time could probably profit off that alone. Quote Link to comment Share on other sites More sharing options...

paparainbow Posted March 6, 2014 Author Share Posted March 6, 2014 Re: rugby in play algorithm for odds compiling do you think using markov chains would do it? assuming you know probabilities for try, drop goa, penalty etc. for each team Quote Link to comment Share on other sites More sharing options...
