A hurdle model is a type of statistical model used primarily for count data that has an excess of zero counts, which it handles by modeling the zeros separately from the positive counts. It combines a binary model to predict zero versus non-zero outcomes and a truncated count model for the positive counts, allowing for greater flexibility in analyzing datasets with many zero values.

A statistical model is a mathematical representation of observed data, capturing relationships between variables and allowing predictions or inferences about the data. It is essential for understanding patterns, testing hypotheses, and making decisions based on data-driven insights.

Count data refers to data that represents the number of occurrences of an event, typically taking non-negative integer values. It is often analyzed using specialized statistical models that account for its discrete nature and potential overdispersion or zero-inflation.

A binary model is a type of statistical or machine learning model that predicts one of two possible outcomes, often represented as 0 and 1. These models are fundamental in classification tasks where the goal is to categorize data points into two distinct classes, such as spam or not spam in email filtering.
