Characteristics of Distance Matrices Based on Euclidean, Manhattan and Hausdorff Coefficients
From n -size samples of k -variate points, we construct n × n distance-matrices based on the widely used Euclidean, Manhattan and Hausdorff coefficients and study (individually and in pairs) their properties P , R and ρ using theoretical analysis and both computer-generated and empirical data. The...
