The big picture: Logistic Model Assessment and Selection
Does a candidate model fit adequately and answer the intended question?
Why a policy analyst should care
Model assessment tests whether a specification serves the intended question and data design; complex surveys require design-adjusted evidence, and improved fit cannot rescue a changed estimand.

2 Explore Compare observed and fitted patterns
3 Formalize Different checks answer different questions
4 Transfer Audit a survey-model decision
