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.

Measures of predictive quality are studied, in particular in survival context, especially in Cox proportional hazards model
