- - INDUS proportion of non-retail business acres per town
- - CHAS Charles River dummy variable (= 1 if tract bounds river; 0 otherwise)
- - NOX nitric oxides concentration (parts per 10 million)
- - RM average number of rooms per dwelling
- - AGE proportion of owner-occupied units built prior to 1940
- - DIS weighted distances to five Boston employment centres
- - RAD index of accessibility to radial highways
- - TAX full-value property-tax rate per $10,000
- - PTRATIO pupil-teacher ratio by town
- - B 1000(Bk - 0.63)^2 where Bk is the proportion of blacks by town
- - LSTAT % lower status of the population
- - MEDV Median value of owner-occupied homes in $1000's
- :Missing Attribute Values: None
- :Creator: Harrison, D. and Rubinfeld, D.L.
- This is a copy of UCI ML housing dataset.

- This dataset was taken from the StatLib library which is maintained at Carnegie Mellon University.
- The Boston house-price data of Harrison, D. and Rubinfeld, D.L. 'Hedonic
- prices and the demand for clean air', J. Environ. Economics & Management,
- vol.5, 81-102, 1978. Used in Belsley, Kuh & Welsch, 'Regression diagnostics
- ...', Wiley, 1980. N.B. Various transformations are used in the table on
- pages 244-261 of the latter.
- The Boston house-price data has been used in many machine learning papers that address regression
- problems.
