Which criterion requires that precision of positive predictions is identical across groups?

Predicative parity, also called predictive rate parity, is about equal precision of positive predictions across groups. Precision of a positive prediction is the positive predictive value: among those the model flags as positive, the proportion who truly are positive. If this value is identical across groups, the reliability of a positive decision is the same no matter which group you look at. Achieving this often means adjusting thresholds group-by-group when base rates differ, so each group maintains the same PPV. The other terms don’t specifically describe this condition: the idea here is focused on equal PPV across groups, while the remaining concepts are broader or unrelated to this particular metric.
