De Boeck's Models

De Boeck's models are statistical frameworks used in educational and psychological testing to understand how different items (questions) relate to underlying traits or abilities, such as intelligence or skill levels. They help analyze test data by modeling how likely a person is to answer correctly based on their ability and the characteristics of each item. These models improve test design and interpretation by accurately capturing the relationship between scores and underlying traits, allowing for more precise measurement of individual abilities or attributes.
