UCI adult income data set, adapted

This data set is adapted from the Adult data from the UCI Machine Learning Repository, which was in turn adapted from Census data on adult incomes and other demographic variables. The UCI data is used here with permission from Ronny Kohavi.

The variables are:

• gt50, which converts the original \>50K variable to an indicator variable; 1 for income greater than $50,000, else 0
• edu, which converts a set of education levels to approximate number of years of schooling
• age
• gender, 1 for male, 0 for female
• mar, 1 for married, 0 for single

Note that the education variable is now numeric.
