Supporting Marketing Applications, medicine. Predictions come from statistical models or algorithms that may be developed with more stringent or more relaxed assumptions. The reliability of predictions suffers from aleatory and epistemic uncertainty, which relate to sample size and broader epidemiologic concepts of generalizability.

We consider simpler approaches and more flexible extensions, including regression trees and neural networks. We also discuss competing risks and the concept of dynamic predi

We briefly review the theoretical background on mechanisms of missingness of predictor values and how these may affect prediction models. We f

SpringerBriefs in Molecular Scienceal studies were available to: (a) quantify predictor effects; (b) develop and validate prognostic models. Missing values were a key issue. Some values were systematically missing per study, since few studies recorded all predictors of interest. The use of single and multiple imputation methods is il

As in any data analysis, we will usually start with obtaining an impression of the data under study, such as the occurrence of missing values and the distribution of predictors and out

A small sample size leads to problems as discussed in Chap. ., such as limited power to test effects of potential predictors, and too extreme predictions when predictions are based on the standard regression coefficients (overfitting
