Details

The samples describe married women who were either not pregnant or do not know if they were pregnant at the time of the interview.

The problem consists in predicting a woman's current contraceptive method choice (here: binarized cont.crit) based on her demographic and socio-economic characteristics.

We made the following enhancements to the original data for improved usability:

  • The criterion was binarized from a class attribute variable with three levels (1 = No-use, 2 = Long-term, 3 = Short-term), into a logical variable (TRUE vs. FALSE).

Other than that, the data remains consistent with the original dataset.
