The influence curves for the correlation coefficients r are drawn as contour plots outside the actual range (-1,1) for 2301 values r = 70(0.01)93 where r has no statistical interpretation.
There, for example, an array of 3x3 'dots' in the middle of the graph grows gradually to an array of 5x5 'dots'. If the demo were continued, the array of 'dots' would grow to arrays of 7x7, 9x9, 11x11,... 'dots'.
It is assumed that n=30, E(X)=E(Y)=0, D(X)=D(Y)=1, and the range for X and Y is (-10,10) in the graph.
Ordinary influence curves for the correlation coefficient r are defined and drawn in an earlier demo
