I am exploring the association between two binary factors using an odds ratio in a large sample that is highly imbalanced: The whole sample contains 150,000 individuals. Witrynaof datasets with imbalanced classes. The most common such measure is the Imbalance Ratio (IR). It is, however, widely accepted that the complexity of a classification task is the combined result of class imbalance and other factors, such as class overlap. Thus, in order to accurately assess the com-plexity of a problem, the data complexity ...
