Adequacy analysis the model of strong replicas agreement in NoSQL databases [PDF]
Компьютерные исследования и моделирование, 2016 In this article the model of strong replicas agreement was analyzed. The process of preparing and conducting the nature experiment in the cloud in order to proof the model adequacy was described.

Modern Stochastics: Theory and Applications, 2016 We consider a stochastic differential equation of the form \[ dX_{t}=\theta a(t,X_{t})\hspace{0.1667em}dt+\sigma _{1}(t,X_{t})\sigma _{2}(t,Y_{t})\hspace{0.1667em}dW_{t}\] with multiplicative stochastic volatility, where Y is some adapted stochastic ...

Monotonic Prefix Consistency in Distributed Systems [PDF]
, 2018 We study the issue of data consistency in distributed systems. Specifically, we consider a distributed system that replicates its data at multiple sites, which is prone to partitions, and which is assumed to be available (in the sense that queries are ...

Strong consistencies of the bootstrap moments [PDF]
International Journal of Mathematics and Mathematical Sciences, 1991 Let X be a real valued random variable with E|X|r+δ < ∞ for some positive integer r and real number, δ, 0 < δ ≤ r, and let {X, X1, X2, …} be a sequence of independent, identically distributed random variables. In this note, we prove that, for almost all w ∈ Ω, with probability 1.

A nonparametric test for comparing survival functions based on restricted distance correlation
Dependence Modeling, 2023 In this article, we propose an omnibus test for comparing two survival functions under non-proportional hazards. The test statistic is based on a product-limit estimate of the restricted distance correlation, which is closely related to the L2{L}_{2 ...

AIMS Mathematics, 2021 Let $ B^{a, b}: = \{B_t^{a, b}, t\geq0\} $ be a weighted fractional Brownian motion of parameters $ a > -1 $, $ |b| < 1 $, $ |b| < a+1 $. We consider a least square-type method to estimate the drift parameter $ \theta > 0 $ of the weighted ...

Strong Consistency of the Good-Turing Estimator [PDF]
2006 IEEE International Symposium on Information Theory, 2006 We consider the problem of estimating the total probability of all symbols that appear with a given frequency in a string of i.i.d. random variables with unknown distribution. We focus on the regime in which the block length is large yet no symbol appears frequently in the string.

Modern Stochastics: Theory and Applications, 2020 The paper deals with a stochastic heat equation driven by an additive fractional Brownian space-only noise. We prove that a solution to this equation is a stationary and ergodic Gaussian process. These results enable us to construct a strongly consistent

Parameter estimation for fractional mixed fractional Brownian motion based on discrete observations
Modern Stochastics: Theory and Applications, 2023 The object of investigation is the mixed fractional Brownian motion of the form ${X_{t}}=\kappa {B_{t}^{{H_{1}}}}+\sigma {B_{t}^{{H_{2}}}}$, driven by two independent fractional Brownian motions ${B_{1}^{H}}$ and ${B_{2}^{H}}$ with Hurst parameters ${H_ ...
