Chi-square distribution calculator.
Calculates a Chi-square distribution over a sequence of bytes within a Buffer.
The result is a float representing the probability of how frequently a truly random sequence of bytes would exceed the calculated value.
Ideally this float should have a value of 0.5. If so, the given Buffer contained random data.
Read on Chi-square distribution for more details.
npm install chi-square
var chiSquare = require'chi-square'crypto = require'crypto';cryptorandomBytes1024 * 1024if err throw err;console.log'The chi square distribution over the random data sequence was: %d' chiSquarecalculatebuffer;;
The output was:
The chi square distribution over the random data sequence was: 0.16175185384825533
