Census Data Example from UC Irvine Machine Learning Repository

Description

Includes a data frame of 1994 US census income from 48,842 people divided into a training set of 32,561 and an independent test set of 16,281. The training outcome variable y (yt for test) is binary and indicates whether or not a person’s income is greater than $50,000 per year. There are 12 predictor variables x (xt for test) consisting of various demographic and financial properties associated with each person. It also included estimates of Pr(y=1|x) obtained by several machine learning methods: gradient boosting on logistic scale using maximum likelihood (GBL), random forest (RF), and gradient boosting on the probability scale (GBP) using least–squares.
