Statistical methods for assessing observer variability in clinical measures.

Statistical methods for assessing agreement

Observer variability in assessing impaired consciousness and coma.

Head-injured patients were examined by a number of observers whose assessments were compared. Considerable discrepancies occurred when overall "levels" of consciousness and coma were used, and also with some terms which are in common use. More consistent assessments were obtained by employing the "Glasgow Coma Scale," which describes eye opening, verbal behaviour, and motor responsiveness. Nurs...

Voronoi Methods for Assessing Statistical Dependence

In this work, we leverage the intuitive geometry of the Voronoi diagram to develop a new class of methods for quantifying and testing for statistical dependence between real-valued random variables. The contributions of this work are threefold: First, we introduce the utility of probability integral transforms of the datapoints to produce Voronoi diagrams which exhibit desirable properties prov...
