Tennis Court Types Interval Dataset

Description

Interval-valued data for tennis players aggregated by court type (Hard, Grass, Indoor, Clay) with weight, height, and racket tension.

Usage

data(tennis.int)

Format

A data frame with 4 observations and 7 columns (3 interval variables in _l/_u Min-Max pairs, plus a label):

• court_type: Type of court (Hard, Grass, Indoor, Clay).

• player_weight_l, player_weight_u: Player weight range (kg).

• player_height_l, player_height_u: Player height range (m).

• racket_tension_l, racket_tension_u: Racket tension range.

Details

Clustering on weight and height separates grass courts from the rest (decision rule: Weight <= 74.75 kg). When all three variables are used, clustering separates by racket tension instead.
