variance

Find the mean of squared deviation of bigints from its mean.

Similar: mean, median, modes, variance, range.

function variance(...xs)
// xs: a list of bigints

const xbigint = require('extra-bigint');


xbigint.variance(1n, 2n);
// → 0n

xbigint.variance(1n, 2n, 3n);
// → 0n

xbigint.variance(1n, 2n, 3n, 4n);
// → 1n
