The paper addresses the issue of comparing deprivation distributions, when deprivation is measured by a sum of binary variables. It provides a graphical device, the Three I’s of Deprivation (TID) curve, that summarizes incidence, intensity and inequality aspects of deprivation. Uncertainty around the estimated deprivation curves is evaluated through simultaneous confidence bands. A hypothesis test of dominance is presented to facilitate the comparison and the ordering of deprivation curves across groups and over time.

摘要

The paper addresses the issue of comparing deprivation distributions, when deprivation is measured by a sum of binary variables. It provides a graphical device, the Three I’s of Deprivation (TID) curve, that summarizes incidence, intensity and inequality aspects of deprivation. Uncertainty around the estimated deprivation curves is evaluated through simultaneous confidence bands. A hypothesis test of dominance is presented to facilitate the comparison and the ordering of deprivation curves across groups and over time.
