To predict profit of a customer more precisely by considering an estimated probability of the customer's contract for a product, an estimated transaction amount in such a product contract, and influences of the product contract on variations in transaction amounts of other contracted products.
Customer information on customer attributes and transaction statuses of customers is input. With the customer information, estimated probabilities of each customer's future contracts are predicted for products registered in advance, and estimated transaction amounts in each customer's future contracts are predicted for the products registered in advance. The estimated product contract probabilities and estimated contracted product transaction amounts both predicted for each customer, and profit rates of the products registered in advance are multiplied together to predict future profits from the products by each customer. Profit variations that each customer's contract for a product with such a predicted future profit causes in the customer's other product transactions are predicted. The future profits from the products by each customer and the predicted profit variations in the other products at the product contract are added together to predict net profits from the products by the customer.
