13                used in the 1983 American Statistical Association Exposition.
14   (c) Date: July 7, 1993

163. Past Usage:
17    -  See 2b (above)
18    -  Quinlan,R. (1993). Combining Instance-Based and Model-Based Learning.
19       In Proceedings on the Tenth International Conference of Machine
20       Learning, 236-243, University of Massachusetts, Amherst. Morgan
21       Kaufmann.

234. Relevant Information:
24
25   This dataset is a slightly modified version of the dataset provided in
26   the StatLib library.  In line with the use by Ross Quinlan (1993) in
27   predicting the attribute "mpg", 8 of the original instances were removed
28   because they had unknown values for the "mpg" attribute.  The original
29   dataset is available in the file "auto-mpg.data-original".
30
31   "The data concerns city-cycle fuel consumption in miles per gallon,
32    to be predicted in terms of 3 multivalued discrete and 5 continuous
33    attributes." (Quinlan, 1993)
34
355. Number of Instances: 398
36
376. Number of Attributes: 9 including the class attribute

43    3. displacement:  continuous
44    4. horsepower:    continuous
45    5. weight:        continuous
46    6. acceleration:  continuous
47    7. model year:    multi-valued discrete
