本文提出了一些新的随机优势(SD)准则来对随机变量上的变换进行排序,这是首次在离散框架下对变换进行排序。利用期望效用理论,给出了一次SD(FSD)一般变换的一个充分条件,并进一步发展为单调变换的充要条件。对于二次SD(SSD)情形,他们将单调变换分为递增和递减两类,并分别推导了它们的充要条件。对于具有相同可能状态的两个不同的离散随机变量,分别得到了FSD和SSD的充要条件。新的SD准则具有如下特点:每个FSD条件用变换函数来表示,每个SSD条件用变换函数和随机变量的概率分布来表征。这与经典的SD方法不同,在经典的SD方法中,FSD和SSD条件用累积分布函数来描述。最后给出了一个数值算例,说明了新的SD准则的有效性。
Abstract This paper presents some new stochastic dominance (SD) criteria for ranking transformations on a random variable, which is the first time that this is done for transformations under the discrete framework. By using the expected utility theory, the authors first propose a sufficient condition for general transformations by first degree SD (FSD), and further develop it into the necessary and sufficient condition for monotonic transformations. For the second degree SD (SSD) case, they divide the monotonic transformations into increasing and decreasing categories, and further derive their necessary and sufficient conditions, respectively. For two different discrete random variables with the same possible states, the authors obtain the sufficient and necessary conditions for FSD and SSD, respectively. The new SD criteria have the following features: each FSD condition is represented by the transformation functions and each SSD condition is characterized by the transformation functions and the probability distributions of the random variable. This is different from the classical SD approach where FSD and SSD conditions are described by cumulative distribution functions. Finally, a numerical example is provided to show the effectiveness of the new SD criteria.
