Lorenz curves and associated tools for ranking income distributions are commonly estimated on the assumption that full, unbiased samples are available. However, it is common to find income and wealth distributions that are routinely censored or trimmed. We derive the sampling distribution for a...

In recent years, there has been a marked decline in the amount of hydrological data being collected in many parts of the developing world. This paper reviews some of the arguments in favour of the continued collection of hydrological data. The technical case is based on the need for long record...
