Resumen
The Zenga distribution is a three-parameter model for non-negative variables that can be used to represent data related to income, financial and actuarial, and also provides measures for interpreting the income inequality. The scale parameter µ is equal to the expected value and does not affect inequality, while the two shape parameters α e θ are indices of inverse and direct inequality, respectively. This paper presents a theoretical introduction of the Zenga distribution, discusses the application of the method of moments as a tool for estimating the model parameters and explores the relationship with the Gini and Zenga inequality indices. As a practical application, the model was fitted to the PNAD Continuous income data for the 1º quarter of 2021 and the results are compared with the estimates of the Gini and Zenga indices for the same period.
