System, including method, apparatus, and computer-readable storage media, for evaluating probabilities of next actions by customers to permit selective customer targeting. Customer data (20) may be received (32). The customer data (20) may represent a plurality of actions (14) taken by customers (12). At least a portion of the customer data (20) may be transformed (34) according to action number into stratified data (80) including strata, with each of the strata representing actions for one or more action numbers (74). A conditional proportional hazard function (84) may be estimated (36) from a stratum of the stratified data (80). Likelihoods of a next action may be calculated (38) using the hazard functions. The likelihoods may be the likelihoods of a next action at one or more times by individual customers (12) whose latest action has an action number for which the stratum represents actions.
