英文摘要:
  We consider properties of the measurement intensity $\\rho$ of a random variable for which the probability density function represented by the corresponding Wigner function attains negative values on a part of the domain. We consider a simple economic interpretation of this problem. This model is used to present the applicability of the method to the analysis of the negative probability on markets where there are anomalies in the law of supply and demand (e.g. Giffen\'s goods). It turns out that the new conditions to optimize the intensity $\\rho$ require a new strategy. We propose a strategy (so-called $\\grave{a}$ rebours strategy) based on the fixed point method and explore its effectiveness.

中文摘要:
我们考虑一个随机变量的测量强度$\\rho$的性质,对于该随机变量,由相应的Wigner函数表示的概率密度函数在域的一部分上达到负值。我们考虑对这个问题的简单经济解释。该模型用于说明该方法在分析市场上的负概率时的适用性,在市场上,供求规律存在异常(例如吉芬的商品)。结果表明,优化强度$\\rho$的新条件需要一种新策略。我们提出了一种基于定点方法的策略(所谓的$\\grave{a}$reboors策略),并探讨了其有效性。
