gini
Calculate the Gini coefficient of a data set.
Installation
Install the package with NPM:
$ npm install -g gini
The -g
flag is recommended for easy CLI usage, but completely optional.
API
For data sets that are already ordered ascendingly, use the faster ordered
function:
var gini = ;var data = 0 2 3 8 9 13 14 23 49 57;var result = gini;console; // = 0.5415730337078651
For data sets that are not already ordered ascendingly, use the slower unordered
function:
var gini = ;var data = 0 14 2 9 3 8 13 23 57 49;var result = gini;console; // = 0.5415730337078651
See here for more information about the two different methods of calculation.
CLI
Run gini
from the command line, with a list of numbers provided as input arguments:
$ gini 0 14 2 9 3 8 13 23 57 49
