Individualised recovery trajectories of patients with impeded mobility, using distance between probability distributions of learnt graphs [PDF]

MSC: primary, 60-XX; secondary, 05C12; 62H20.Patients who are undergoing physical rehabilitation, benefit from feedback that follows from reliable assessment of their cumulative performance attained at a given time. In this paper, we provide a method for

On comprehensive families of copulas involving the three basic copulas and transformations thereof

Dependence Modeling
Comprehensive families of copulas including the three basic copulas (at least as limit cases) are useful tools to model countermonotonicity, independence, and comonotonicity of pairs of random variables on the same probability space. In this contribution,

A dimension reduction for extreme types of directed dependence

Dependence Modeling
In recent years, a variety of novel measures of dependence have been introduced being capable of characterizing diverse types of directed dependence, hence diverse types of how a number of predictor variables X = (X 1, …, X p), p∈N $p\in \mathbb{N ...

Multivariate measures of positive dependence

, 2008
In this paper a set of desirable properties for measures of positive dependence of ordered n-tuples of continuous random variables (n ≥ 2)is proposed and a class of multivariate positive dependence measures is introduced.

Bernstein-based nonparametric estimation of the cross ratio function under univariate right censoring

Dependence Modeling
Bivariate time-to-event data often arise in various fields, including medicine, engineering, and economics, where understanding the association between two survival times is crucial. Traditional global association measures like Spearman’s rho and Kendall’

Towards a Theory of Negative Dependence

, 1999
: The FKG theorem says that the POSITIVE LATTICE CONDITION, an easily checkable hypothesis which holds for many natural families of events, implies POSITIVE ASSOCIATION, a very useful property.

Ascertaining the Underlying Distribution of a Data Set

, 1994
We combine the concept of maximum correlation between two random variables with the Principal Coordinate Analysis technique, to propose a descriptive procedure to ascertain the underlying probability distribution of a univariate sample.

SFB 823 Nonparametric inference on Lévy measures and copulas Discussion Paper Nonparametric inference on Lévy measures and copulas

, 2020
In this paper nonparametric methods to assess the multivariate Lévy measure are introduced. Starting from high-frequency observations of a Lévy process X, we construct estimators for its tail integrals and the Pareto Lévy copula and prove weak ...

Functional genetics of hereditary and sporadic uterine leiomyomas. [PDF]

, 2006
Uterine leiomyomas (fibroids) are common benign neoplasms arising from the smooth muscle layer of the uterus, the myometrium. Despite their prevalence in reproductive age women, little is understood of their pathobiology. The work in this thesis examined

Metric Scaling Graphical Representation of Categorical Data

, 1995
: Metric Scaling is a well--known method to represent a finite set with respect to a given Euclidean distance matrix. Several methods to represent rows and columns of a two--way contingency table are available: Correspondence Analysis, Dual Scaling ...
