Bundesliga Data 2014/15 (Buli1415)

Description

Data from the German Bundesliga from the season 2014/15. The data contain all 306 matches of the season treated as paired comparisons with 5 (Y5) or 3 (Y3) different response categories. Additionally, different match-specific covariates are given as, for example, the percentage of ball possession or the total running distance per team and per match.

Format

A list containing data from the German Bundesliga with 306 observations. The list contains both information on the response (paired comparisons) and different covariates.

Y5

A response.BTLLasso object with 5 response categories for the Buli1516 data including

  • response: Ordinal paired comparison response vector

  • first.object: Vector containing the first-named team per paired comparison (home team)

  • second.object: Vector containing the second-named team per paired comparison (away team)

  • subject: Vector containing a match-day identifier per paired comparison

  • with.order Vector containing information that each match has to be considered including an order effect.

Y3

A response.BTLLasso object with 3 response categories for the Buli1516 data including

  • response: Ordinal paired comparison response vector

  • first.object: Vector containing the first-named team per paired comparison (home team)

  • second.object: Vector containing the second-named team per paired comparison (away team)

  • subject: Vector containing a match-day identifier per paired comparison

  • with.order Vector containing information that each match has to be considered including an order effect.

Z1

Matrix containing all team-match-specific covariates

  • Distance: Total amount of km run

  • BallPossession: Percentage of ball possession

  • TacklingRate: Rate of won tacklings

  • ShotsonGoal: Total number of shots on goal

  • CompletionRate: Percentage of passes reaching teammates

  • FoulsSuffered: Number of fouls suffered

  • Offside: Number of offsides (in attack)
