Yahtzee: An Anonymized Group Level Matching Procedure
The dark line represents the accuracy rate for true participators. The light line represents the accuracy rate for true abstainers. Accuracy increases for both categories as observations for each individual are obtained from the Yahtzee procedure. Note that the less frequent of the two behaviors requires fewer observations for classification than the more frequent behavior. is the number of observations per person necessary to achieve a given level of accuracy for the less frequent behavior and is the number of observations necessary to achieve a given level of accuracy for the more frequent behavior.
