Convergence to infinitely divisible distributions with finite variance for some weakly dependent sequences

Jérôme Dedecker, Sana Louhichi (2005)

ESAIM: Probability and Statistics

We continue the investigation started in a previous paper, on weak convergence to infinitely divisible distributions with finite variance. In the present paper, we study this problem for some weakly dependent random variables, including in particular associated sequences. We obtain minimal conditions expressed in terms of individual random variables. As in the i.i.d. case, we describe the convergence to the gaussian and the purely non-gaussian parts of the infinitely divisible limit. We also discuss...

Convergence to stable laws and a local limit theorem for stochastic recursions

Mariusz Mirek (2010)

Colloquium Mathematicae

We consider the random recursion X x = M X n - 1 x + Q + N ( X n - 1 x ) , where x ∈ ℝ and (Mₙ,Qₙ,Nₙ) are i.i.d., Qₙ has a heavy tail with exponent α > 0, the tail of Mₙ is lighter and N ( X n - 1 x ) is smaller at infinity, than M X n - 1 x . Using the asymptotics of the stationary solutions we show that properly normalized Birkhoff sums S x = k = 0 n X k x converge weakly to an α-stable law for α ∈ (0,2]. The related local limit theorem is also proved.
