Using Random Forest to Learn Imbalanced Data

2.1 Random Forest Random forest (Breiman, 2001) is an ensemble of unpruned classification or regression trees, induced from bootstrap samples of the training data, using random feature selection in the tree induction process. Predic-tion is made by aggregating (majority vote for classification or averaging for regression) the predictions of

Fixed-Effect Versus Random-Effects Models

In Chapter 11 and Chapter 12 we introduced the fixed-effect and random-effects models. Here, we highlight the conceptual and practical differences between them. Consider the forest plots in Figures 13.1 and 13.2. They include the same six studies, but the first uses a fixed-effect analysis and the second a random-effects analysis.
