Hi guys, I need your help.
I’m just performing an analysis over some supplier’s bids, and my objective is to spot any unsual relation between bidders. In this case, I have done some graphics in powerbi which are visually effective, but my intention is to capture these cases through a knime workflow. In the picture presented below there are bid rounds (X axis) and bid amounts (y axis). Each line is a vendor.
In this example , there is a clear relation in the way bids are changing among suppliers (they almost all increase or decrease in the same rounds, and in similar amounts) I have been trying in KNIME the “Linear Correlation” node, but it gives me some contradictory results (probably I’m not configuring it properly). My input data table is very simple:
|Round||Vendor 1||Vendor 2||Bidd amount 1||Bidd amount 2|
Which is the best way to measure this kind of relation?
thank you very much.
