**TLDR:** A foundational classification algorithm that uses the logit function to model class probabilities.

<p>Despite its name, logistic regression is one of the most fundamental algorithms used in practice for classification problems. The model estimates the probability that an observation belongs to a given class and makes a decision based on that probability. Because of its high interpretability, it is widely used in healthcare, finance, marketing, and risk modeling. Its probabilistic output also allows decision thresholds to be adjusted according to business objectives.</p>
