Objective To identify and estimate the population costs and effects of a selected set of enforcement strategies for reducing the burden of road traffic injuries in developing countries. Design Cost effectiveness analysis based on an epidemiological model. Setting Two epidemiologically defined...

In studies that compare Internet use between groups, factor analysis is often used to create broader categories of use. Composite variables are constructed using a factor structure that fits the overall data. This approach overlooks tests that show whether the constructs are valid and whether...

We assess measurement error in panel survey reports of social security benefit receipt, drawing on a unique validation study. Our aims are threefold. First, we quantify the incidence of measurement errors (under- and over-reporting). Second, we assess the extent to which this varies according to...

There is a duality theory connecting certain stochastic orderings between cumulative distribution functions F1 , F2 and stochastic orderings between their inverses F −1 , F −1. This underlies some theories of utility in the case of the cdf and deprivation indices in the case of the inverse....
