Hierarchical Symbolic Dataset with Mixed Types

Description

Mixed symbolic dataset of 10 observations with hierarchical categorical variables, conditional histogram variables, and an interval-valued variable. From Table 6.20 of Billard and Diday (2007).

Usage

data(hierarchy.hist)

Format

A symbolic data frame (symbolic_tbl) with 10 observations and 7 variables:

• duration_time: Histogram-valued duration (2-bin).

• hierarchy_1: Categorical hierarchy level 1 (a/b/c).

• hierarchy_2: Categorical hierarchy level 2 (a1/a2), conditional on hierarchy_1 = a.

• hierarchy_3: Categorical hierarchy level 3 (a11/a12), conditional on hierarchy_2 = a1.

• glucose: Histogram-valued glucose (2-bin), conditional.

• pulse_rate: Histogram-valued pulse rate (2-bin), conditional.

• cholesterol: Interval-valued cholesterol level.
