For example, for a twodimensional space with 10000 points the expected distance is D(2,10000) = 0.0005 and for a 10-dimensional space with the same number of sample points D(10,10000) = 0.4. 7 2 = 1/8   ( xi – 4.375)2 i=1 Use an appropriate nonlinear transformation (one of those represented in Figure 4.5) to improve regression results...
