On account of the lack of monetary unit sampling( MUS), an extended audit game model based on uncertainty information,which centers on audit risk and combines audit game with statistical sampling,is established to improve the effectiveness of audit risks analysis and sampling errors control. In this paper,an example concerning practical problems is given to demonstrate the process of extended audit game and confirm the truth of the effectiveness of the method. Not only does this method enhance the role of audit technology and the extension of audit procedures in deterring material irregularities,but also helps the auditors measure and control audit risk and sample sizes under uncertainty,conducive to improving the effect of cost control,risk evaluation,and decisionmaking optimization in audit sampling.
