# Math Help - what is O(du^2)

1. ## what is O(du^2)

or O(dudv)

as in this expression: Order statistic - Wikipedia, the free encyclopedia

This is the first time I came across this function(?) - in the proof of the density of the ith order statistics.

2. So that's what it's called! Cheers!

I am not sure if I am ready yet for these articles, matheagle, but I will put them in my file )))

3. The point is, I work with order stats.
