The Three I’s of Deprivation (TID) Curves: Estimation, Inference, and Stochastic Dominance

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.
