In dataSDA: Datasets and Basic Statistics for Symbolic Data Analysis

Horse Breeds Interval Dataset

Description

Interval-valued data for 8 horse breeds (CES, CMA, PEN, TES, CEN, LES, PES, PAM) described by 6 variables: minimum/maximum weight, minimum/maximum height, cost of mares, cost of fillies.

Usage

data(horses.int)

Format

A symbolic data frame (symbolic_tbl) with 8 observations and 7 variables:

• Breed: Horse breed code (CES, CMA, PEN, TES, CEN, LES, PES, PAM; character).

• Minimum_Weight: Minimum weight range (kg, interval).

• Maximum_Weight: Maximum weight range (kg, interval).

• Minimum_Height: Minimum height range (cm, interval).

• Maximum_Height: Maximum height range (cm, interval).

• Mares_Cost: Cost of mares range (currency units, interval).

• Fillies_Cost: Cost of fillies range (currency units, interval).

Details

Extensively used in SDA for demonstrating divisive clustering, distance computation, hierarchy/pyramid construction, and complete objects.
