考虑如下问题：已知测量误差的频率分布，由一组考生的观测分数分布确定或估计真分数的分布。通常，这个问题没有唯一的解决方案。然而，如果真分数分布是“平滑的”，那么问题的任何两个平滑解决方案将彼此相差不大。方法寻找光滑的解决方案，开发a）为一个人口和B）为一个样本的考生。对实际测试数据的一些试验结果进行了总结。
The following problem is considered: Given that the frequency distribution of the errors of measurement is known, determine or estimate the distribution of true scores from the distribution of observed scores for a group of examinees. Typically this problem does not have a unique solution. However, if the true-score distribution is “smooth,” then any two smooth solutions to the problem will differ little from each other. Methods for finding smooth solutions are developed a) for a population and b) for a sample of examinees. The results of a number of tryouts on actual test data are summarized.
