The big picture: The Logistic Curve
How can a linear predictor produce probabilities between zero and one?
Why a policy analyst should care
The logistic curve converts an unbounded linear score into a valid probability and explains why the same coefficient produces different probability changes at different baselines.
Follow the idea from the opening question to a practical decision. These are the conceptual moves this module will develop:
1 Question How can probability change without becoming impossible?
2 Explore Move the curve on two scales
3 Formalize Anatomy of a simple logistic regression
