Model comparison is the systematic evaluation and contrast of two or more predictive models against shared criteria to determine relative performance and suitability for a given task. Its parameters are: (1) a set of candidate models to compare, (2) a set of evaluation criteria (e.g., accuracy, AIC, BIC, cross-validated error, interpretability), (3) a held-out or resampled evaluation protocol that ensures fair assessment, and (4) a decision rule that selects or ranks models based on the criteria. It persists as a structured practice implemented through statistical tests (e.g., paired t-tests, McNemar's test), information criteria (AIC, BIC), and resampling-based procedures.

Definition
Why it is in scope
Model comparison is a human-made analytical framework for evaluating and contrasting two or more predictive models against each other using shared criteria such as accuracy, complexity, interpretability, and generalization performance. It is a constructed set of methods and principles — including statistical tests, cross-validation schemes, and information-theoretic scores — built to persist as a systematic way to decide between competing models.

Model comparison is the practice of evaluating and comparing statistical models using criteria like AIC, BIC, cross-validation. Remove statistics and model comparison cannot operate — these are fundamentally statistical procedures. The removal test passes.

Model comparison is a specific kind of methodology — a systematic approach for evaluating and comparing different models against criteria. A competent speaker would call model comparison a methodology for model selection.
