A latent variable model for the analysis of variability in the classification of radiographs of pneumoconioses

The interpretation of chest radiographs for pneumoconioses is subjective and susceptible to inter- and intra-observer variability. The Istatistic has traditionally been used to assess interobserver agreement. In this paper a different paradigm for the analysis of radiographic readings for pneumoconiosis is introduced. This framework involves log-linear modelling and considers the radiograph and the reader together. The results of the analysis …
