Statistical Parametric Analysis on Democracy Data

摘要

The Economist Intelligence Unit (EIU), collected information from 167 countries of the world to classify each of the countries into four categories of Democracy and they have classified those countries based on the Democracy Index Score (DIS). EIU derived the DIS from the subject data and proceeded descriptively to use the DIS score to classify each of the countries into one of the four types of democracy . In this paper, we have identified the overall probability density function (PDF) of the DIS as well as the PDF of each of the individual type of democracy defined by EIU. Knowing the PDF it can probabilistically characterize the behavior of the overall DIS data and each of the four types of democracy. It is found that the overall PDF of DIS is mixer distribution with their corresponding weights and some of the PDF of individual category follows the same probability density function.
