The following example shows the use of DescTools In bag Gini() Function calculation R Two methods of Gini coefficient in .

Example 1： Use personal income to calculate Gini coefficient

Suppose we have the following 10 Personal annual income list ：

income ：5 Thousands of dollars 、5 Thousands of dollars 、7 Thousands of dollars 、7 Thousands of dollars 、7 Thousands of dollars 、9 Thousands of dollars 、15 Thousands of dollars 、15 Thousands of dollars 、15 Thousands of dollars 、15 Thousands of dollars
