Predicting Purchases, Rare Diseases, and More: Using Ordinal Regression to Estimate Rare Event Probabilities
Estimating probabilities of rare events like purchases from click ads or contracting rare diseases is difficult because of class imbalance. In this talk, I will show how ordinal regression can make these estimation problems easier. I will explain the methods step-by-step, show you real data examples, and share code implementing the methods.
