Interval-valued data for tennis players aggregated by court type
(Hard, Grass, Indoor, Clay) with weight, height, and racket tension.
Usage
data(tennis.int)
Arguments
Format
A data frame with 4 observations and 4 variables:
court_type: Type of court (Hard, Grass, Indoor, Clay).
player_weight: Player weight range (kg).
player_height: Player height range (m).
racket_tension: 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.
