Error decomposition is the process of breaking down the total prediction or estimation error of a model into distinct components, typically to better understand where inaccuracies come from. In statistical learning, this often appears as bias-variance-noise decomposition, which separates systematic error (bias), sensitivity to data fluctuations (variance), and irreducible randomness (noise). In other contexts, error decomposition can refer to partitioning measurement error into random and systematic parts, or splitting forecast errors into different contributing factors. The goal is to diagnose model performance, guide model selection and improvement, and clarify the sources and structure of uncertainty in predictions.
