Exclusions

EMULDUR 381 A (Z68-40339) => This product is the only one tagged with a (3RD PARTY) manufacturing plant and has a high price, therefore it brings by its own the SHAP value of the manufacturing_plant_code feature way higher than it should be. To avoid this happening, we decided to exclude this product for now.

Fluids

A big part of the weights (almost 50%) is focused on product_fluid_type only. This feature alone will define most of the comparable set. This should be considered when analyzing results of this family.

Exclusions

The following products in the fluids family (Galden, Fomblin, Fluorolink) are sold at very high prices and low volumes. Having a few of them as comparable for a CPC could bring the median way higher than expected. If we include these products, their associated CPCs also end up with a price decrease recommendation of about 95% of the price.

Note that since they often have dedicated fluid type, we might be able to use "product_fluid_type" or a derived new column of the taxonomy to identify these products to either filter them out or add a hard-boundary to compare them altogether and not with the rest of the data.

The red dots on the far right of the "product_fluid_type" SHAP values correspond to these products
