Which guideline for deciding on the number of MDS dimensions relies on theory or past research to suggest the number of dimensions?
A) interpretability of the spatial map

C) ease of use
D) a priori knowledge

Question

Quizplus · Accepted Answer

A priori knowledge involves using theoretical or past research to provide guidance on the number of dimensions in MDS analysis. This approach is more robust than relying on interpretability, ease of use, or the elbow criterion alone.
