Non-Gaussian gravitational clustering field statistics
large-scale structure of Universe – galaxies clusters
2011/3/2
In this work we investigate the multivariate statistical description of the matter distribution
in the nonlinear regime.
Connectivity statistics of store-and-forward inter-vehicle communication
Connectivity statistics store-and-forward inter-vehicle communication
2010/12/28
Inter-vehicle communication (IVC) enables vehicles to exchange messages within a limited broadcast range and thus self-organize into dynamical vehicular ad hoc networks. For
the foreseeable future, h...
Delayed feedback causes non-Markovian behavior of neuronal firing statistics
Delayed feedback non-Markovian behavior neuronal firing statistics
2011/3/4
The instantaneous state of a neural network consists of both the degree of excitation of each neuron, the network is composed of, and positions of impulses in communication lines between neurons.
On moments of lower generalized order statistics from exponentiated Pareto distribution and its characterization
Lower generalized order statistics lower records single moments
2010/11/1
In this paper we establish explicit expressions and some recurrence relations for single and product moments of lower generalized order statistics from exponentiated Pareto distribution. The results i...
Shannon entropy for the Feller-Pareto (FP) family and order statistics of FP subfamilies
Burr distribution Entropy Feller-Pareto distribution
2010/9/20
In this paper, we derive the exact analytical expressions of entropy for the FellerPareto(FP) family and order statistics of FP subfamilies. The FP family is a very general unimodal distribution which...

Non-Gaussian gravitational clustering field statistics
2011/1/4
In this work we investigate the multivariate statistical description of the matter distribution in the nonlinear regime. We introduce the multivariate Edgeworth expansion of the lognormal distribution...
Two-Point Vorticity Statistics in the Inverse Turbulent Cascade
Two-Point Vorticity Statistics Inverse Turbulent Cascade
2010/12/28
We present a statistical analysis of the two-point vorticity probability density of the vorticity eld generated in the inverse cascade of stationary two-dimensional turbulence.
Spectral Statistics of "Cellular" Billiards
Chaotic Dynamics(nlin.CD) Mathematical Physics(math-ph) Spectral Theory(math.SP)
2010/11/10
For a bounded planar domain $\Omega^0$ whose boundary contains a number of flat pieces $\Gamma_i$ we consider a family of non-symmetric billiards $\Omega$ constructed by patching several copies of $\O...
L-cumulants, L-cumulant embeddings and algebraic statistics
L-cumulant embeddings algebraic statistics
2010/11/12
In this paper we generalize the combinatorial definition of cumulants. Obtained in this way L-cumulants keep all the desired properties of the classical cumulants like semi-invariance and vanishing f...
Matching Statistics of an Itô Process by a Process of Diffusion Type
Matching Statistics Process of Diffusion Type
2010/11/8
Suppose we are given a multi-dimensional It\^o process, which can be regarded as a model for an underlying asset price together with related stochastic processes, e.g., volatility. The drift and diff...
We study polytopes that are convex hulls of vectors of subgraph densities. Many graph theoretical questions can be expressed in terms of these polytopes, and statisticians use them to understand expon...
Transformation & Uncertainty. Some Thoughts on Quantum Probability Theory, Quantum Statistics, and Natural Bundles
Quantum Probability Theory Quantum Statistics Natural Bundles
2010/11/19
This PHD thesis is concerned with uncertainty relations in quantum probability theory, state estimation in quantum stochastics, and natural bundles in differential geometry. After some comments on the...

Spectral statistics random Schrö dinger operators the localized regime
2010/11/15
We study various statistics related to the eigenvalues and eigenfunctions of random Hamiltonians in the localized regime. Consider a random Hamiltonian at an energy $E$ in the localized phase. Assume ...

Higher order statistics annulus square billiard: transport polyspectra
2010/12/15
Classical transport in a doubly connected polygonal billiard, i.e. the annulus square billiard, is considered. Dynamical properties of the billiard flow with a fixed initial direction are analyzed by ...
U-Quantile Processes and Generalized Linear Statistics of Dependent Data
L-Statistic U-statistics U-quantiles Bahadur representation mixing near epoch dependence
2010/12/14
Generalized linear statistics are a unifying class that contains U-statistics,U-quantiles, L-statistics as well as trimmed and winsorized U-statistics. For example, many commonly used estimators of sc...
