auto_mpg {s2net}

Auto MPG Data Set

Description

This dataset was taken from the UCI Machine Learning Repository https://archive.ics.uci.edu/ml/datasets/Auto+MPG, and processed for the semi-supervised setting (Ryan and Culp, 2015).

Usage

data("auto_mpg")

Format

There are two lists that contain partitions from a data frame with 398 observations on the following 9 variables.

mpg

a numeric vector

cylinders

an ordered factor with levels 3 < 4 < 5 < 6 < 8

displacement

a numeric vector

horsepower

a numeric vector

weight

a numeric vector

acceleration

a numeric vector

year

a numeric vector

origin

a factor

Details

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 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)
