    Chi-Square

    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.

    Installation

    npm install chi-square

    Examples

    var chiSquare = require('chi-square'),
        crypto = require('crypto');
     
    crypto.randomBytes(1024 * 1024, function(err, buffer) {
        if (err) throw err;
     
        console.log('The chi square distribution over the random data sequence was: %d', chiSquare.calculate(buffer));
    });

    The output was:

    The chi square distribution over the random data sequence was: 0.16175185384825533
