I'm looking for some direction on the proper way to cluster forward commodity curves based on their day over day returns.
I've worked on clustering in the past but I only dealt with spot prices rather than a full forward curve. For instance I would want to try and which forward curves move similarly across the full length of the curve rather than treat each forward month as a standalone price. Here's a simple example on the data in case I'm not describing it well:
|Date||Curve Name||Forward Month||Price|
