Details

The data consist of \(n=534\) observations, with the response being a Bernoulli variable of whether they were a member of union (1 = yes; 0 = no), and six covariates: gender (1 = female, 0 = male), race (1 = white; 0 = other), an indicator variable for whether the worker lives in the south (1 = yes; 0 = no), age in years, hourly wage, and number of years in education.

One of the aims of the survey is to uncover associations between workers' characteristics and their probability of union membership. The dataset is used in Ruppert et al., (2003) and Hui et al. (2018), among others, to illustrate the application of Semiparametric regression, as it is believed that union membership may vary non-linearly with the three continuous variables (age, wage, education).
