A data.frame with 9275 observations on 11 variables:

• e401k: =1 if eligble for 401(k)

• inc: annual income, $1000s

• marr: =1 if married

Notes

This data set can also be used to illustrate the binary response models, probit and logit, in Chapter 17, where, say, pira (an indicator for having an individual retirement account) is the dependent variable, and e401k [the 401(k) eligibility indicator] is the key explanatory variable.
