or yes
.arsenic
distance
education
association
no
or yes
.The data are for an area of Arahazar upazila, Bangladesh. The researchers labelled each well with its level of arsenic and an indication of whether the well was ``safe'' or ``unsafe.'' Those using unsafe wells were encouraged to switch. After several years, it was determined whether each household using an unsafe well had changed its well. These data are used by Gelman and Hill (2007) for a logistic-regression example.
