Webfunction from caret is used. Here, we simulate a separate training set and test set, each with 5000 observations. Additionally, we include 20 meaningful variables and 10 noise variables. The intercept argument controls the overall level of class imbalance and has been selected to yield a class imbalance of around 50:1.

WebUnderstanding the decision tree structure. ¶. The decision tree structure can be analysed to gain further insight on the relation between the features and the target to predict. In this example, we show how to retrieve: the nodes that were reached by a sample using the decision_path method; the decision path shared by a group of samples. WebThe Weighted Method Count (WMC) of a class is a good indicator of how much time and effort is required to modify and maintain this class. The WMC metric is defined as the sum of complexities of all methods declared in a class. A large number of methods also means that this class has a greater potential impact on derived classes. Example: :
