本文导出了Rasch模型的条件或伪精确检验的幂函数的一般表达式。它允许确定条件检验对各种备选假设的功效。讨论了实践中经常出现的一些相关实例。在计算方面，提出了一种蒙特卡罗方法，使近似的确切功率的应用。
In this paper, a general expression of the power function of conditional or pseudo-exact tests of the Rasch model is derived. It allows the determination of the power of conditional tests against various alternative hypotheses. A number of relevant examples frequently occurring in practice are discussed. With respect to computations, a Monte Carlo approach is suggested enabling the approximation of the exact power in applications.
