Overdue repayment probability prediction method and device and nonvolatile storage medium

The invention discloses an overdue repayment probability prediction method and device and a nonvolatile storage medium. The method comprises the steps that transaction characteristics of N objects in a target card using period are acquired, the N objects comprise a target object and other objects associated with the target object, and N is an integer larger than 1; according to the transaction characteristics, a transaction characteristic set corresponding to the target object is determined, and the transaction characteristic set comprises the transaction characteristics of the target object and the transaction characteristics of other objects; and based on the transaction feature set, determining an overdue repayment probability of the target object, the overdue repayment probability representing a repayment probability of the target object after a repayment deadline corresponding to the target card use period. The technical problem of inaccurate probability prediction result of overdue repayment of the targ
