# average

Calculate the average of a sequence and its error iteratively, using constant
memory and avoiding numerical problems. The calculation can be easily parallelized
by using `Average::merge`.

## Advantages over naive calculation of average and variance

* Avoids loss of precision due to cancellation.
* Only needs a single pass over the samples, at the cost of a division inside the loop.
