METHODS AND APPARATUS FOR ESTIMATING A LORENZ CURVE FOR A DATASET BASED ON A FREQUENCY VALUE ASSOCIATED WITH THE DATASET

摘要

Methods and apparatus for estimating a Lorenz curve for a dataset based on a frequency value associated with the dataset are disclosed. An example apparatus for estimating a Lorenz curve for a dataset representing a distribution of products for individual members of a population includes a frequency identifier and a Lorenz curve generator. The frequency identifier is to access a frequency value associated with the dataset. The frequency value is derived from an occurrence value associated with the products of the dataset and a population value associated with the individual members of the population of the dataset. The frequency identifier is to access the frequency value without directly accessing the occurrence value and the population value. The Lorenz curve generator is to generate an estimated Lorenz curve for the dataset using a Lorenz curve estimation function including the frequency value.
