Searching With Measurement Dependent Noise [PDF]
IEEE Transactions on Information Theory, 2014 Consider a target moving at a constant velocity on a unit-circumference circle, starting at an arbitrary location. To acquire the target, any region of the circle can be probed to obtain a noisy measurement of the target's presence, where the noise level increases with the size of the probed region.

Plug-in Estimation of Dependence Characteristics of Archimedean Copula via Bézier Curve
Revstat Statistical Journal, 2023 This article introduces measurement of the dependence between variables with a dependence structure defined by Archimedean copulas. The estimation of the dependence measure, such as Kendall’s tau as well as the lower and upper tail dependence, is ...

Dependence Estimation and Visualization in Multivariate Extremes with Applications to Financial Data [PDF]
, 2003 We investigate extreme dependence in a multivariate setting with special emphasis on financial applications. We introduce a new dependence function which allows us to capture the complete extreme dependence structure and present a nonparametric ...

Hidden Markov Models as a Tool for the Assessment of Dependence of Phenomena of Economic Nature
Acta Universitatis Lodziensis. Folia Oeconomica, 2018 The assessment of dependence between time series is a common dilemma, which is often solved by the use of the Pearson’s correlation coefficient. Unfortunately, sometimes, the results may be highly misleading.

Measurable Sensitivity for Semi-Flows
Mathematics, 2023 Sensitive dependence on initial conditions is a crucial characteristic of chaos. The concept of measurable sensitivity (MS) was introduced as a measure-theoretic version of sensitive dependence on initial conditions.

Stochastic models which separate fractal dimension and Hurst effect [PDF]
, 2001 Fractal behavior and long-range dependence have been observed in an astonishing number of physical systems. Either phenomenon has been modeled by self-similar random functions, thereby implying a linear relationship between fractal dimension, a measure ...

A Class of Association Measures for Categorical Variables Based on Weighted Minkowski Distance
Entropy, 2019 Measuring and testing association between categorical variables is one of the long-standing problems in multivariate statistics. In this paper, I define a broad class of association measures for categorical variables based on weighted Minkowski distance.

Executive Functions in Tobacco Dependence: Importance of Inhibitory Capacities. [PDF]
PLoS ONE, 2016 BACKGROUND:Executive functions are linked to tobacco dependence and craving. In this cross-sectional study, we assessed the impact of three executive functions: updating, inhibition and shifting processes on tobacco craving and dependence.

Dependence measure for length-biased survival data using copulas
Dependence Modeling, 2019 The linear correlation coefficient of Bravais-Pearson is considered a powerful indicator when the dependency relationship is linear and the error variate is normally distributed.

Intermittency of trawl processes [PDF]
, 2017 We study the limiting behavior of continuous time trawl processes which are defined using an infinitely divisible random measure of a time dependent set. In this way one is able to define separately the marginal distribution and the dependence structure.
