\title{Hierarchical Symbolic Dataset with Mixed Types}
\format{
A symbolic data frame (\code{symbolic_tbl}) with 10 observations
and 7 variables:
\itemize{
    \item \code{duration_time}: Histogram-valued duration (2-bin).
    \item \code{hierarchy_1}: Categorical hierarchy level 1 (a/b/c).
    \item \code{hierarchy_2}: Categorical hierarchy level 2 (a1/a2), conditional on hierarchy_1 = a.
    \item \code{hierarchy_3}: Categorical hierarchy level 3 (a11/a12), conditional on hierarchy_2 = a1.
    \item \code{glucose}: Histogram-valued glucose (2-bin), conditional.
    \item \code{pulse_rate}: Histogram-valued pulse rate (2-bin), conditional.
    \item \code{cholesterol}: Interval-valued cholesterol level.
