It is shown that in some characterizations of the Gaussian distribution, through natural properties of linear forms of independent, possibly equidistributed random variables, instead of the -algebra generated by one of the forms one can restrict oneself to the finite-dimensional space of polynomials of this form. Thus, the corresponding characterization theorems are significantly refined.Translated from Zapiski Nauchnykh Seminarov Leningradskogo Otdeleniya Matematicheskogo Instituta im. V. A.

A local limit theorem is given for independent noninteger random variables under a condition which is more general than one previously given, and which reduces, in the case of identically distributed random variables, to a well-known result. 相似文献

(B)If L exists, then L<∞ if and only if R<∞, and when L is finite, L=Ef(S)+R.
Applications are given to infinite series of independent random variables, and to normed sums of independent, identically

We provide a bound on a distance between finitely supported elements and general elements of the unit sphere of . We use this bound to estimate the Wasserstein-2 distance between random variables represented by linear combinations of independent random variables. Our results are expressed in terms of a discrepancy measure related to Nourdin–Peccati’s Malliavin–Stein method. The main application is towards the computation of quantitative rates of convergence to elements of the second Wiener chaos. In particular, we explicit these rates for non-central asymptotic of sequences of quadratic forms and the behavior of the generalized Rosenblatt process at extreme critical exponent. 相似文献

We present upper bounds of the integral \( {\int}_{-\infty}^{\infty }{\left|x\right|}^l\left|\mathbf{P}\left\{{Z}_N<x\right\}-\varPhi (x)\right|\mathrm{d}x \) for 0 ≤ l ≤ 1 + δ, where 0 < δ ≤ 1, Φ(x) is a standard normal distribution function, and Z N = \( {S}_N/\sqrt{\mathbf{V}{S}_N} \) is the normalized random sum with variance V S N > 0 (S N = X 1 + · · · + X N ) of centered independent random variables X 1 ,X 2 , . . . . The number of summands N is a nonnegative integer-valued random variable independent of X 1 ,X 2 , . . . . 相似文献

Summary A certain transformation of distribution functions (d.f.'s) of positive random variables (r.v.'s) has been studied by the
author and Harkness in [2] and [3]. In this paper, a limit theorem concerning such a transform of convolutions of d.f.'s is
proved. 相似文献

In this paper we study the limiting behavior of sums of dependent random variables under a strong mixing condition. We obtain
conditions for which an analog of the Baum-Katz theorem holds and cite an example showing their optimality.

The bounded-dual-Lipschitz and Prohorov distances from the ‘empirical measure’ to the ‘average measure’ of independent random variables converges to zero almost surely if the sequence of average measures is tight. Three examples are also given. 相似文献
