正在考虑的是一组二元项目的测试。假设n个个体的响应遵循Rasch模型。进一步假设潜在个体参数在给定总体内按照正态分布分布分布。方法，然后被认为是估计这一潜在的人口分布的均值和方差。还考虑了检查正态总体分布是否符合数据的方法。所开发的方法适用于数据从成绩测试和态度测试。
Under consideration is a test battery of binary items. The responses of n individuals are assumed to follow a Rasch model. It is further assumed that the latent individual parameters are distributed within a given population in accordance with a normal distribution. Methods are then considered for estimating the mean and variance of this latent population distribution. Also considered are methods for checking whether a normal population distribution fits the data. The developed methods are applied to data from an achievement test and from an attitude test.
