When dealing with prediction, statistical models have to fit some criteria. The requirements are different for marginal predictions and for individual predictions. Based on two exemples in oncology, particularities and criteria of prognostic models are explored. The first exemple deals with the margianl effect of breast cancer chemoprevention on overall survival for women at high risk. The second exemple deals with individual prediction with a marginal model for Hodgkin's lymphoma patients. Measures of predictive quality are studied, in particular in survival context, especially in Cox proportional hazards model
