Reviving this thread, doing any type of simple statistics is more verbose than it probably needs to be as calculating sums, averages, etc. makes most resort to Array reduction. I understand the need for methods such as `Math.hypot(...values)`, but for ECMAScript to evolve to be useful in statistics programming without needing to resort to R would definitely also be a nice-to-have. I'm sure there are many statistical functions you *could* add, but at a bare minimum, it would be useful:
Math.sum(...values) or Math.summation(...values) Math.mean(...values) // Spelling out mean here is succinct while still intentional, instead of .avg Math.variance(...values) Math.stddev(...values) Obviously some of these can be computed from the results of others, but I think the convenience and intent of the methods, not to mention their wide usefulness outweigh the concern of Math bloat. Thoughts? P.S. Definitely not against even more core stats methods, but have to start somewhere. :) Eli Perelman Mozilla
