When a prognostic model performs less well in a new population, using the new data to modify the model should first be considered rather than directly developing a new model. A major emphasis is given to linear regression for continuous outcomes, logistic regression for binary outcomes, and Cox regression and parametric survival models for time-to-event outcomes.
