The column name "score" suggests an accumulated or assigned quantity. Strong additive signals: 82.6% zeros (against multiplicative), large unbounded magnitude (max 258,873, mean 10,736), center far from 1.0, strictly non-negative. The distribution is extensive and accumulative, consistent with a count-like or point-based scoring system. Real_additive is the clear fit; sum is the natural aggregation for combining scores across entities. </reasoning> <table_type_conflict>false</table_type_conflict> </result> ```
