An interactive, BASIC-PLUS, simulation program is described for performing a large number of multivariate analyses in accord with, or in violation of, known underlying models. Using a PDP 11/40 computer, random numbers are generated and converted into bivariate normal observations X and Y. These data are then analyzed according to three models. The three analyses are: (1) a standard analysis of variance ignoring the concomitant variable; (2) an analysis of covariance; (3) an analysis of variance on the ratio Y/X. The program can be used to examine the effect of performing multivariate analyses on data transformed into ratios. The utility of the program is the simplicity with which one can alter the underlying models and/or the mathematical relationships between X and Y. Output provides comparisons between models by accumulating rejections and other statistics on critical F-values for each model.
描述了一个交互式的、BASIC-PLUS模拟程序，用于根据已知的基础模型或违反已知基础模型进行大量的多变量分析。使用PDP 11/40计算机生成随机数，并将其转换为双变量正态观测值X和Y。然后根据三种模型对这些数据进行分析。这三种分析是：(1) 忽略伴随变量的标准方差分析；(2) 协方差分析；(3) Y/X比值的方差分析。该程序可用于检验对转换为比值的数据进行多变量分析的效果。该程序的实用性在于，用户可以轻松改变基础模型和/或X与Y之间的数学关系。输出通过累积每个模型的关键F值的拒绝次数和其他统计量，提供模型之间的比较。
