Extracting product drag effect from transaction records

A computer system for computing a product drag effect, comprising:

• one or more processors, one or more computer-readable memories, one or more computer-readable tangible storage medium, and program instructions stored on at least one of the one or more tangible storage medium for execution by at least one of the one or more processors via at least one of the one or more memories, wherein the computer system is capable of performing a method comprising:
• receiving a plurality of transaction record data;
• tuning a plurality of parameters based on the received transaction record data;
• determining a product drag frequency based on the authorized parameter tuning and received transaction record data;
• calculating a drag probability based on the determined product drag frequency;
• deriving an observation from the calculated drag probability;
• and
• outputting the derived observation to a user.
