A collection of bookmakers' football odds (for home win/draw/away win, expressed as ternary probabilistic forecasts) and subsequent results. The data cover several years of English league games.
The quoted odds, transformed to probabilities, are in foot$p (a 3-column matrix). The corresponding results of the games are in foot$o (a 3-column matrix).
Data taken from www.football-data.co.uk.
