Calculation method
Calculation method
Pairwise shared product counts
Count product-ID intersection for every unordered collection pair.
Pairwise Jaccard overlap (%)
Intersection/union×100; two empty sets are explicitly undefined rather than assumed identical.
Distinct products across all collections
Count the union of all supplied product IDs.
Products exclusive to each collection
List IDs in one collection and absent from every other supplied collection.
Products present in multiple collections
List IDs with membership in at least two collections.
Symbols and units
- a
- Collections: name, product IDs joined by | or none
Use the units shown. A list keeps the order in which you enter its values. The symbol ^ means “raised to the power of”.
Assumptions & limits
Assumptions & limits
- A provided-ID assortment overlap audit with no similarity inference. Results depend on consistent product identity and the set of collections supplied.
