ABSTRACT
We propose a convenient method of estimating the within-group, between-group, and interaction components of the overall traditional Gini index from the estimated parameters of underlying "trick regression models" involving known forms of heteroscedasticity related to income. Two illustrative examples involving both real and artificial data are provided. The issue of appropriate standard error of the subgroup decomposition is also discussed.

    Given a directed source-sink network whose arcs either function or fail with known probabilities, we define the reliability of a node as the probability that there exists a path from the network's source to the node that consists only of functioning arcs.
