Question

Quizplus · Accepted Answer

The guideline that warns about the difficulty in interpreting configurations or maps derived in more than three dimensions is the interpretability of the spatial map. Therefore, the best choice is D. The elbow criterion refers to selecting the number of dimensions that explain most of the variability in the data. A priori knowledge can be used to guide the choice of the number of dimensions, but it is not always available. Ease of use is a subjective criterion that depends on the user's experience and preferences.
