Boston house prices dataset
**Data Set Characteristics:**
Number of Instances: 506
Number of Attributes: 13 numeric/categorical predictive. MedianValue (attribute 14) is usually the target.
Attribute Information (in order):
- CRIM per capita crime rateby town
- ZN proportion ofresidential land zoned for lots over 25,000 sq.ft.
- INDUS proportion ofnon-retail business acres per town
- CHAS Charles River dummyvariable (= 1 if tract bounds river; 0 otherwise)
- NOX nitric oxidesconcentration (parts per 10 million)
- RM average number ofrooms per dwelling
- AGE proportion ofowner-occupied units built prior to 1940
- DIS weighted distances tofive Boston employment centres
- RAD index ofaccessibility to radial highways
- TAX full-valueproperty-tax rate per $10,000
- PTRATIO pupil-teacher ratioby town
- B 1000(Bk - 0.63)^2where Bk is the proportion of blacks by town
- LSTAT % lower status of thepopulation
- MEDV Median value ofowner-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 maintainedat Carnegie Mellon University.The Boston house-price data of Harrison, D. andRubinfeld, 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 ofthe latter.
The Boston house-price data has been used in many machine learningpapers that address regressionproblems.

- INDUS 每个城镇的非零售商业面积所占比例
- CHAS Charles-River虚拟变量(=1,如果是河流边界,则为0;否则为0)
- NOX 氮氧化物浓度(百万分之几)
- RM 每间住宅的平均房间数
- AGE 1940年以前建造的自住单位的年龄比例
- DIS 离波士顿五个就业中心的距离
- RAD 辐射状公路可达性指数
- TAX 每万元房产税完税率
- PTRATIO按城镇划分的师生比例
- B 1000(Bk-0.63)^2,其中Bk是按城镇划分的黑人比例

这个数据集取自卡内基梅隆大学的StatLib图书馆大学。那个Harrison,D.和Rubinfeld,D.L.的波士顿房价数据,“享乐价格和对清洁空气的需求”,J.Environ。《经济学与管理》,第5卷,81-1021978年。用于Belsley,Kuh&Welsch,“回归诊断…”,Wiley,1980年。N、 B.后者第244-261页的表格中使用了各种变换。
波士顿房价数据已被用于许多机器学习论文,以解决回归问题。
