Car Evaluation Database was derived from a simple hierarchical decision model
originally developed for the demonstration of DEX, M. Bohanec, V. Rajkovic:
Expert system for decision making.

datasets

Algorithms and methods for model-based clustering and classification.
It supports various types of data: continuous, categorical and counting
and can handle mixed data of these types. It can fit Gaussian (with diagonal
covariance structure), gamma, categorical and Poisson models. The algorithms
also support missing values.
