Sum

mctad.sum() accepts an Array of Numbers and returns their sum as a Number. It is used in the calculation of mctad.arithmeticMean(), the Arithmetic Mean.

mctad.sum = function (data) { if (!Array.isArray(data) || data.length === 0 ) { return undefined; }

sum is a simple accumulator.

var sum = 0.0; for (var i = 0; i < data.length; i++) { sum += data[i]; } return sum; };
