Declaration:  TCurveFit.KruskalGamma: double; 
The readonly property KruskalGamma returns Kruskal's gamma value which is a measure of the strength of dependence between the x and yvalues entered by the method EnterStatValue. Note, that at least 3 data pairs have to be entered to calculate a valid coefficient.

Hint: 
The execution time of this routine increases with the square of the number of data points. Thus it is not recommended to calculate Kruskal's gamma for more than 10000 data points.
