1. Title: Auto-Mpg Data
|
|
|
|
2. Sources:
|
|
(a) Origin: This dataset was taken from the StatLib library which is
|
|
maintained at Carnegie Mellon University. The dataset was
|
|
used in the 1983 American Statistical Association Exposition.
|
|
(c) Date: July 7, 1993
|
|
|
|
3. Past Usage:
|
|
- See 2b (above)
|
|
- Quinlan,R. (1993). Combining Instance-Based and Model-Based Learning.

4. Relevant Information:
|
|
|
|
This dataset is a slightly modified version of the dataset provided in
|
|
the StatLib library. In line with the use by Ross Quinlan (1993) in
|
|
predicting the attribute "mpg", 8 of the original instances were removed
|
|
because they had unknown values for the "mpg" attribute. The original
|
|
dataset is available in the file "auto-mpg.data-original".
|
|
|
|
"The data concerns city-cycle fuel consumption in miles per gallon,
|
|
to be predicted in terms of 3 multivalued discrete and 5 continuous
|
|
attributes." (Quinlan, 1993)
|
|
|
|
5. Number of Instances: 398
|
|
|
|
6. Number of Attributes: 9 including the class attribute
|
|
|
|
7. Attribute Information:
|
|
|
|
1. mpg: continuous
|
|
2. cylinders: multi-valued discrete
|
|
3. displacement: continuous
|
|
4. horsepower: continuous
|
|
5. weight: continuous
|
|
6. acceleration: continuous
|
|
7. model year: multi-valued discrete
|
|
8. origin: multi-valued discrete
|
|
9. car name: string (unique for each instance)
|
|
|
|
8. Missing Attribute Values: horsepower has 6 missing values
