Quantifying radiological changes in simple pneumoconiosis
Methods of handling data arranged in ordered categories are reviewed in the context of radiological classifications of simple pneumoconiosis. Assumptions required for analyses of proportions, of scores corresponding to the natural numbers and of Normalized scores are discussed critically. Temporal extrapolation of changes in ordered classifications is considered using a Markov model.
