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. In Proceedings on the Tenth International Conference of Machine Learning, 236-243, University of Massachusetts, Amherst. Morgan Kaufmann. 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 " "0" "'autoMpg.names'" 12 11.5 11 12 10.5 10 9 8.5 10 8.5 10 8 9.5 10 15 15.5 15.5 16 14.5 20.5 17.5 14.5 17.5 12.5 15 14 15 13.5 18.5 14.5
