In rater: Statistical Models of Repeated Categorical Rating Data

Dentist ratings of whether caries are healthy or not based on X-rays

Description

It consists of binary ratings, made by 5 dentists, of whether a given tooth was healthy (sound) or had caries, also known as cavities. The ratings were performed using X-ray only, which was thought to be more error-prone than visual/tactile assessment of each tooth. In total 3,689 ratings were made. This data is in 'grouped' format. Each row is one of the 'pattern' with the final columns being a tally of how many times that pattern occurs in the dataset.
