Ensemble of Decision Tree Classifiers for Mining Web Data Streams
... tree structure from class-labeled training examples. A decision tree has three main components: nodes, leaves, and edges. Each node is labeled with an attribute by which the data is to be partitioned. Each node has a number of edges, which are labeled according to possible values of the attribute. A ...

This approach is essentially a marginal structural binomial model for the effect of a point treatment. Relative and absolute effect measures (e.g. risk ratios and risk differences) may be obtained f ...

chi-square test
... The chi-square test, in general, can be used to check whether an empirical distribution follows a specific theoretical distribution. Chi-square is calculated by finding the difference between each observed (O) and theoretical or expected (E) frequency for each possible outcome, squaring them, dividi ...
