Using the nationally representative Slan dataset of 2007 we analyse the relationship between self-reported and measured BMI. We find that self-reported BMI significantly underestimates obesity rates and suggest that the traditional threshold of 30 should be adjusted downwards. We outline a...

Classification accuracy is the ability of a marker or diagnostic test to discriminate between two groups of individuals, cases and controls, and is com- monly summarized by using the receiver operating characteristic (ROC) curve. In studies of classification accuracy, there are often covariates...
