论文摘要
本文研究了最佳选择的选择概率（从提供的套装中挑选最佳和最差的替代方案）。结果表明，最佳偏斜块 - 摩chak多项式的非负性是必需的，足以足以存在随机效用表示。该代表定理是通过扩展Falmagne（1978）采用的证明技术来获得最佳选择的相应结果（从提供的集合中选择最佳替代方案）获得的。
This paper investigates best-worst choice probabilities (picking the best and the worst alternative from an offered set). It is shown that non-negativity of best-worst Block-Marschak polynomials is necessary and sufficient for the existence of a random utility representation. The representation theorem is obtained by extending proof techniques employed by Falmagne (1978) for a corresponding result on best choices (picking the best alternative from an offered set).
