The Lorenz and the scaled total-time-on-test transform curves: A unified approach

The strong relationship between the Lorenz and scaled total time-on-test transform curves allows measures devised separately for the fields of economics and reliability to be applied to the other field as well. This article shows that, more accurately, the Gini-index and Pietra-ratio can be useful in reliability analysis and that several other questions remain to be explored. Associated graphical methods can be very useful within an integrated approach. A user-friendly computer software developed by the authors is useful to theoreticians and practitioners alike.<
