Abstract:

We introduce a new notion of central axis for a finite set { a 1 , , a m } equ1 of vectors in R n equ2 . In tandem, we discuss different ways of measuring the dispersion of the data points a i equ3 ‘s around the central axis. Finally, we explain how to detect numerically the most peripheral points of the given dataset.
