Each term of fraction difference has value between 0 and 1. The Canberra distance itself is not between zero and one. If one of coordinate is zero, the term become unity regardless the other value, thus the distance will not be affected. Note that if both coordinate are zeros, we need to be defined as . This distance is very sensitive to a small change when both coordinate near to zero. Formula
Exercise: For example:
Point A has coordinate (0, 3, 4, 5) and point B has coordinate (7, 6, 3, 1). The Canberra Distance between point A and B is The pattern of Canberra distance in 2dimension is almost quadrilateral with asymptotic curve in one of the edges. The figure below is drawn with sink at the center. Compare this with the 2D shape of Bray Curtis distance. See Also: Bray Curtis distance References:
