The Cumulative Logit Model is a statistical technique used for modeling ordinal response variables, where the response categories have a natural order. It estimates the probability of an observation falling into or below a particular category by using a logistic function to model the cumulative probabilities of the ordered categories.

The logistic function is a mathematical function that models growth processes which are initially exponential but slow down as they approach a maximum limit, commonly used in logistic regression for binary classification. It is characterized by its S-shaped curve, representing how growth accelerates to a point and then decelerates as it approaches the carrying capacity.

Ordered categories, also known as ordinal data, represent data that have a meaningful sequence but lack a consistent difference between categories. This type of data is often used in surveys and questionnaires where responses are ranked or rated, such as satisfaction levels or frequency of occurrence.
