The Reliability of Subjective Probabilities Obtained Through Decomposition
讨论了分解方法如何提高主观概率编码的一致性，通过心理测量模型分析分解估计的随机误差，并与直接评估比较误差变化，为利用分解控制误差提供建议。
The use of decomposition as a procedure for improving the consistency of subjective probability encoding is discussed. Using a psychometric measurement model, an expression is developed that describes the random error associated with decomposition estimates as a function of characteristics of the component assessments. Decomposition is compared to direct assessment in terms of the percent change in measurement error that can be attributed to the use of decomposition. Potential benefits of decomposition are specified and recommendations made on how to utilize decomposition as an approach for error control.
