Alex Herbert updated STATISTICS-32:
-----------------------------------
    Description: 
Sibling issue to: STATISTICS-31

It is useful to know the [survival 
function|https://en.wikipedia.org/wiki/Survival_function] of a number given a 
discrete distribution.

While this can be approximated with
{noformat}
1 - cdf(x){noformat}
, there is an opportunity for greater accuracy in certain distributions.
