title: A Score Matrix for Thurstone's Box Problem.
abstract: 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.
