Rate Distortion Theory for Descriptive Statistics

open access: yesEntropy, 2023
Rate distortion theory was developed for optimizing lossy compression of data, but it also has applications in statistics. In this paper, we illustrate how rate distortion theory can be used to analyze various datasets.

Statistical Theories of Success [PDF]

open access: yesProceedings of the National Academy of Sciences, 1970
The Pareto and the log-normal distributions are commonly used to describe the statistical distribution of success. A detailed comparison of these distributions is made with Lotka's extensive observations on success as measured by rate of publication.

The Quality of Reserve Risk Calculation Models under Solvency II and IFRS 17

open access: yesRisks, 2022
We analyse four stochastic claims reserving methods in terms of their capability to estimate reserve risk and how successful they are at predicting distributions and VaRs of claim developments in particular.

On the Statistical Theory of Turbulence [PDF]

open access: yesProceedings of the National Academy of Sciences, 1937
G. I. Taylor (1) gave an important impetus to the statistical theory of turbulence by introducing the concept of "isotropic" turbulence, defined by the feature that the mean squares and mean products of the velocity components and of their derivatives are invariant with respect to rotation and reflection of the coordinate axes.

General Conditions of Weak Convergence of Discrete-Time Multiplicative Scheme to Asset Price with Memory

open access: yesRisks, 2020
We present general conditions for the weak convergence of a discrete-time additive scheme to a stochastic process with memory in the space D [ 0 , T ] . Then we investigate the convergence of the related multiplicative scheme to a process that can

Statistical Theory of Superlattices [PDF]

open access: yesProceedings of the Royal Society of London. Series A - Mathematical and Physical Sciences, 1935
Abstract In a recent paper, Bragg and Williams have pointed out that the arrangement of the atoms in an alloy depends in a striking way on the temperature. At high temperatures, the atoms are distributed practically at random among the lattice points of the crystal, but at low temperatures a superlattice may be formed such that the ...

Investigation of sample paths properties for some classes of φ-sub-Gaussian stochastic processes

open access: yesModern Stochastics: Theory and Applications, 2021
This paper investigates sample paths properties of φ-sub-Gaussian processes by means of entropy methods. Basing on a particular entropy integral, we treat the questions on continuity and the rate of growth of sample paths.

On Drift Parameter Estimation in Models with Fractional Brownian Motion by Discrete Observations

open access: yesAustrian Journal of Statistics, 2014
We study a problem of an unknown drift parameter estimation in a stochastic differen- tial equation driven by fractional Brownian motion. We represent the likelihood ratio as a function of the observable process.

Gaussian Volterra processes with power-type kernels. Part II

open access: yesModern Stochastics: Theory and Applications, 2022
In this paper the study of a three-parametric class of Gaussian Volterra processes is continued. This study was started in Part I of the present paper.
