PredictorMeasurements[predictor, testset, prop] gives measurements associated with the property prop when predictor is evaluated on testset.

• PredictorMeasurements[predictor, testset] yields a measurement report that can be applied to any property.
• PredictorMeasurements[data, ...] use predictions data instead of a predictor.
• PredictorMeasurements[..., {prop1, prop2, ...}] gives properties prop1, prop2, etc.
