foot: Football betting dataset

In ternvis: Visualisation, Verification and Calibration of Ternary Probabilistic Forecasts

Football betting dataset

Description

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.

Usage

data(foot)

Format

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).

Source

Data taken from www.football-data.co.uk.

Examples

data(foot)
# see the distribution of forecasts
tplot(foot$p,main="Bookmaker forecasts of \n football matches",
      dimnames=c("Home Win","Draw","Away Win"))
      
# see how well forecasts compare with results
# create object of class tverify
foot.verify <- tverify(p=foot$p,o=foot$o) 

# plot ternary reliability diagram
dev.new()
plot(foot.verify, thresh=3)    
           
# get a (linear) calibration of these data
# create an object of class tverify
foot.calib <- tgetcal(foot.verify) 

# plot ternary reliability diagram of calibrated forecasts       
dev.new()
plot(foot.calib, thresh=3)
