How do you estimate CLV with BG/NBD and Gamma-Gamma?

BG/NBD predicts future transactions in a noncontractual setting; Gamma-Gamma can model their mean value under additional assumptions. CLV then discounts the expected flows.

Direct answer

Rank customers by expected future value with temporal validation.

BG/NBD predicts future transactions in a noncontractual setting; Gamma-Gamma can model their mean value under additional assumptions. CLV then discounts the expected flows.

Model or deliverableC_t = V_t × margin_rate_t; CLV = Σt E[N_t × C_t | history]/(1+d)^t; factorization requires declared conditional independence and d must use the same period as t
