Data Analysis Using the Concentration Function
DOI:10.1002/wics.70048.png)
Abstract
En 中文
Several notions of concentration function have been proposed in the statistical literature. Here we will refer to the definition by Cifarelli and Regazzini (1987), used for the comparison of probability measures in very general probability spaces. We will consider the concentration function in more restricted settings, typically those of interest to practitioners, that is, discrete or absolutely continuous (with respect to the Lebesgue measure) probability measures. We will show how a sophisticated mathematical tool can be used to provide graphs and indices that are easily interpreted by practitioners. Some examples will support this statement.
