Abstract: | The beginnings of a system of interactive multidimensional scaling programs with real-time display of the graphical output have been established on the Honeywell DDP-224 computer. Two programs have been completed: (1) MDPREF—a computer program for multidimensional analysis of preference data—has been converted from the GE-635 to run interactively on the DDP-224 computer. Its solution is printed from a typewriter, and the configuration of stimuli are displayed on a scope in two-dimensional view. (2) ROTATE—an on-line rotation program—enables the user to rotate the configuration in three dimensions within a higher dimensional space. |
