I'm glad we've cleared that up but is it reasonable to say that if f = Op(n-1/4) then for large n f grows at the same rate as n-1/4?

The O's should actually be Op's (my mistake) and x is a set of random variables. I don't think this changes the nature of the question drastically. Note that the result f(x) = Op(x-1/4) is quite common so it can't be a meaningless statement.

I understand the formal definition for big O notation but is there an intuitive interpretation?. For example, if f(x) = O(x-1/4) is it reasonable to say that for large n f(x) grows at the same rate as n-1/4? Thanks in advance

Homework Statement I have E(a) = 0, E(b) = x but E(|a+b|)=?? where E is the expectations operator and x is a known constant which is greater than zero. Homework Equations Any one know how I would go about determining E(|a+b|)?
