Clarifying the standard deviational ellipse

Auteur :
GONG, J.

Description :
Standard deviational ellipse is not at all an ellipse. The main focus of the paper is to clarify mathematically the actual shape of this curve and to discuss its applications in spatial analysis. This shape changes from a single circle to double circles when the distribution of the set of geographical units changes from an even condition to a straight line.
