Since the score matrix for Thurstone's classic 20-variable box problem contains no measurement error and also genera1,es a singular correlation matrix, a new score matrix for this problem, both containing measurement error and having enough entities to yield a nonsingular correlation matrix, is developed. Various interesting statistics for the new data are given, and an extended vector projection for the new data is shown. The new score matrix should be of use for work in factor-analytic methodology.
由于瑟斯顿经典的20变量盒式问题的得分矩阵不包含测量误差，且生成的是奇异相关矩阵，因此针对该问题开发了一种新的得分矩阵，它既包含测量误差，又有足够的实体以产生非奇异相关矩阵。给出了新数据的各种有趣统计量，并展示了新数据的扩展向量投影。新的得分矩阵应该对因子分析方法的研究有用。
