3、ption(PDD)data.1.2 Any test data analysis procedure used shall be correctlymatched to the PDD examination format.Examiners shall useevaluation methods for which they have been formally trained.1.2.1 Acceptable test data analysis procedures are thosepublished in refereed or technical journals,and for

11、re not suitable,no evaluation shall beundertaken for the purpose of diagnosing truthfulness ordeception.Nothing shall preclude an evaluator from reportingevidence of countermeasures when this evidence exists.3.1.1.3 Use analysis methods generally recognized to beaccurate.3.1.2 When possible,numerica
12、l evaluation shall be pre-ferred over global evaluation.3.2 Numerical Evaluation:3.2.1 Evaluators employing numerical evaluation shall firstverify that the PDD recordings are suitable for evaluation.Ifthey are not suitable,no evaluation shall be undertaken for thepurpose of diagnosing truthfulness o
