A multicriteria discrimination approach to model qualified audit reportsA multicriteria discrimination approach to model qualified audit reports Peer-Reviewed Journal Publication Δημοσίευση σε Περιοδικό με Κριτές 2015-11-182004enThis study investigates the contribution of financial and non-financial information to enhance the ability to discriminate between the choices of a qualified or unqualified (clean) audit report. The audit firms face the risk of losing the client if they issue a qualification. On the other hand, failing to qualify exposes the auditor to lawsuits and reputations loss. Financial statements, auditors’ opinions, and the notes to financial statements are examined for a sample of 100 firms. The auditors’ qualification decision is modelled using a multicriteria decision aid classification method (MHDIS-Multi-groupHierarchicalDIScrimination). A comparison with statistical techniques (linear discriminant analysis and logit analysis) is also performed. This study has implications for internal and external auditors and company decisions makers.http://creativecommons.org/licenses/by/4.0/Operational Research, An International Journal43347-355 Michael Doumpos Δουμπος Μιχαλης Zopounidis Konstantinos Ζοπουνιδης Κωνσταντινος Spathis, Charalambos T Springer Verlag Qualified audit report Financial statements Multicriteria decision aid Classification
