- Hello there !!
I have following problem concerning a condition of type Lindeberg:
Assume we have:
An(eps)=Mn^(2d) sum[z in Vn, E(Xnz^2 Ind( |Xnz|>= eps / Mn^(2d) )] --> 0 (n-->oo) for all eps>0
where Mn is a sequence of natural numbers, E means expected value, Xnz are random variables,
Ind means indicator function.
Now with this assumption following is true, but i cannot figure it out. I think it is rather a calculus problem than a stochastic one:
The assumption above implies that there exists a positive, non-increasing null sequence (eps_n), n>=1 satisfying An(eps_n) / eps_n --> 0 as n --> oo.
How can I see this and how can I construct such a sequence ?
Every help is appreciated !!
