comp.pred

<code>comp.pred</code> provides a wrapper for many classification algorithms --- such as CART (<code><a href="/link/rpart%3A%3Arpart?package=FFTrees&version=1.7.0" data-mini-rdoc="FFTrees::rpart::rpart">rpart::rpart</a></code>),
logistic regression (<code>glm</code>), support vector machines (<code>svm::svm</code>), and random forests (<code><a href="/link/randomForest%3A%3ArandomForest?package=FFTrees&version=1.7.0" data-mini-rdoc="FFTrees::randomForest::randomForest">randomForest::randomForest</a></code>).

Create, visualize, and test fast-and-frugal decision trees (FFTs) using the algorithms and methods described in Phillips, Neth, Woike & Gaissmaier (2017).
FFTs are simple and transparent decision trees for solving binary classification problems.
FFTs can be preferable to more complex algorithms because they require very little information, are easy to communicate, and are robust against overfitting.
