I have two curves extracted from some data and I'm trying to detect when there is a difference. Each of these 3 plots represents a different data set.
From these example curves below, I'm looking for a metric that I can use to compare the green and blue plots. These are normalised plots.
The Left and Right plots are examples of a matching case. The middle plot is an example of non-matching data set.
I've tried using Chi-Square and Bhattacharyya distance but neither give good separation between data sets.
Any suggestions?
