I have two data sets. One is points in the blue curve. The other is points in the green curve. Now I want to find a property (P) or something else like index that has the following characteristics:
- It represents the similarity between two data sets. (With similarity I am referring to the same shapes plot by these points of two data sets)
- It doesn't depend on the scale. Two shapes have the same shape but different scale still give the same P value.
