Zusammenfassung: | PROBLEM TO BE SOLVED: To highly accurately estimate a user's survival rate.SOLUTION: An information acquisition unit 34 acquires purchase history from a purchase history storage device 4 on the basis of a condition inputted from a user terminal 1 and a preprocessing unit 36 generates input data from the acquired purchase history. A parameter estimation unit 38 and a cluster specification unit 40 repeat operation for determining a purchase cycle parameter λ of each user and a withdrawal parameter μ of each user on the basis of a coefficient matrix of each of predetermined marketing variables in a cluster to which the user belongs, determining the cluster to which each user belongs and estimating a coefficient matrix in each cluster. A statistic value calculation unit 42 estimates a user's survival rate on the basis of the user's purchase cycle parameter λ and the user's withdrawal parameter μ which are repeatedly determined, and a display unit 44 displays the estimated result on the user terminal 1. |
