Notes and Communications ON SENSITIVITY ANALYSIS IN DECISION THEORY*
指出Evans在决策敏感性分析文章中的关键错误，提供正确的概率空间距离公式，并提醒读者注意被忽略的先前研究。
ABSTRACT This note points out a crucial flaw in Evans's recent article [1] on decision sensitivity analysis which was published in this journal. This flaw leads to errors in the majority of his formulae and examples. Correct distance formulae in “probability space,” easily computed from the problem data, are provided. After a critical discussion of some of the concepts Evans employed, we bring to the reader's attention a body of prior work in this area that apparently was overlooked.
