max :: (Typed a, Ord a) => Int -> Stream a -> Stream a

Maximum value.

min :: (Typed a, Ord a) => Int -> Stream a -> Stream a

Minimum value.

sum :: (Typed a, Num a, Eq a) => Int -> Stream a -> Stream a

Summation.

mean :: (Typed a, Eq a, Fractional a) => Int -> Stream a -> Stream a

Mean value. n must not overflow for word size a for streams over which computation is peformed.

meanNow :: (Typed a, Integral a) => [Stream a] -> Stream a

Mean value over the current set of streams passed in.
