comment Name for resistance to change in data
So how would I calculate the sample variance with one data point ($=\frac{1000}{1010}$ or $=\frac{100}{101}$)?

Well, the problem is that I only have one data point, which makes all those formulas useless. If it helps, think about these numbers as the ratings for a bookseller on say...Amazon. Someone with 1000 positive votes and 10 negative is much more likely to be reliable than someone with 100 positive and 1 negative...

Right, I know about standard deviance. However, I don't see a way to calculate that from just those numbers.

I didn't really want to edit the original question to put this, but do you also know of where I can find ways to calculate the degree of robustness?

comment Bulgarian Solitaire: Size of root loops
@Gerry: Really? I did a search for "bulgarian solitaire" and only got three relevant results, none of which were papers. Additionally, are these papers you speak of behind a pay-wall?

"Permutation"s should have been "partition"s
