Find Chi Square, P-value, Degree of Freedom of a contingency Table ie, two dimensional array
A working sample can be seen here http://statpages.info/chisq.html
npm install chi-square-p-value
In your file
import Analyse from 'chi-square-p-value';
const contingencyTable = [
[23, 126],
[3, 8],
[1, 6],
[2, 0]
];
/****
* chi - Chi Square value
* df - Degree of Freedom
* pValue - P Value
* residual - Adjusted Residual values of array
***/
const { chi, df, pValue, residual } = Analyse(contingencyTable);
