چکیده

A strictly stationary sequence of random variables is constructed with the following properties: (i) the random variables take the values −1 and +1 with probability 1/2 each, (ii) every five of the random variables are independent of each other, (iii) the sequence is “causal” in a certain sense, (iv) the sequence has a trivial double tail σ-field, and (v) regardless of the normalization used, the partial sums do not converge to a (nondegenerate) normal law. The example has some features in common with a recent construction (for an arbitrary fixed positive integer N), by Alexander Pruss and the author, of a strictly stationary N -tuplewise independent counterexample to the central limit theorem.

A Strictly Stationary, N-tuplewise Independent Counterexample to the Central Limit Theorem

For an arbitrary integer N ≥ 2, this paper gives a construction of a strictly stationary, N -tuplewise independent sequence of (nondegenerate) bounded random variables such that the Central Limit Theorem fails to hold. The sequence is in part an adaptation of a nonstationary example with similar properties constructed by one of the authors (ARP) in a paper published in 1998. AMS 2000 Mathematic...

Central Limit Theorems For Superlinear Processes

The Central Limit Theorem is studied for stationary sequences that are sums of countable collections of linear processes. Two sets of sufficient conditions are obtained. One restricts only the coefficients and is shown to be best possible among such conditions. The other involves an interplay between the coefficients and the distribution functions of the innovations and is shown to be necessary...

Central Limit Theorem in Multitype Branching Random Walk

A discrete time multitype (p-type) branching random walk on the real line R is considered. The positions of the j-type individuals in the n-th generation form a point process. The asymptotic behavior of these point processes, when the generation size tends to infinity, is studied. The central limit theorem is proved.

Almost Sure Central Limit Theorem for Strictly Stationary Processes

On any aperiodic measure preserving system, there exists a square integrable function such that the associated stationary process satifies the Almost Sure Central Limit Theorem. Introduction The Almost Sure Central Limit Theorem (ASCLT), first formulated by Lévy in [9], has been studied by various authors at the end of the eighties ([6], [3], [10], [8]). This theorem gives conditions under whic...

Asymptotic results for spatial causal ARMA models

The paper establishes a functional central limit theorem for the empirical distribution function of a stationary, causal, ARMA process given by Xs,t = i≥0 j≥0 a i,j ξ s−i,t−j , (s, t) ∈ Z 2 , where the ξ i,j are independent and identically distributed, zero mean innovations. By judicious choice of σ−fields and element enumeration, one dimensional martingale arguments are employed to establish t...
