A Note on Compounding Probabilities in Auditing.
研究了审计风险公式在条件性修订审计计划或评估审计结果时的局限性，指出实际最终风险可能小于或大于各风险乘积，并提供了控制风险的方法。
Abstract Many auditors believe that the risk formula in the appendix of SAS No. 39 has value as a simplified means of considering the relationships among different types of audit evidence and in evaluating different audit strategies in developing an overall audit plan. However, use of the formula to conditionally revise an audit plan or to evaluate audit results may subject the auditor to more risk than would seem to be indicated by such use of the formula. In this paper we show some conditions for which the realized ultimate risk is less than or equal to the product of the separate risks, and conditions for which the realized risk can be greater. For the latter cases we show alternative means of controlling the realized ultimate risk.
