Skorokhod M1 convergence of maxima of multivariate linear processes with heavy-tailed innovations and random coefficients

open access: yesModern Stochastics: Theory and Applications
In this paper, functional convergence is derived for the partial maxima stochastic processes of multivariate linear processes with weakly dependent heavy-tailed innovations and random coefficients. The convergence takes place in the space of ${\mathbb{R}^

Generation and Detection of Multivariate Regular Variation and Hidden Regular Variation

open access: yes, 2014
We review definitions of multivariate regular variation (MRV) and hidden regular variation (HRV) for distributions of random vectors and then summarize methods for generating models exhibiting both properties. We also discuss diagnostic techniques that detect these properties in multivariate data and indicate when models exhibiting both MRV and HRV are

Estimation of extreme risk regions under multivariate regular variation [PDF]

open access: yesThe Annals of Statistics, 2011
When considering d possibly dependent random variables, one is often interested in extreme risk regions, with very small probability p. We consider risk regions of the form ${\mathbf{z}\in\mathbb{R}^d:f(\mathbf{z})\leqβ}$, where f is the joint density and $β$ a small number.

Multivariate Regular Variation [PDF]

open access: yes, 2020
In insurance and reinsurance, heavy-tail analysis is used to model insurance claim sizes and frequencies in order to quantify the risk to the insurance company and to set appropriate premium rates.

WEARCON: wearable home monitoring in children with asthma reveals a strong association with hospital based assessment of asthma control

open access: yesBMC Medical Informatics and Decision Making, 2020
Background Asthma is one of the most common chronic diseases in childhood. Regular follow-up of physiological parameters in the home setting, in relation to asthma symptoms, can provide complementary quantitative insights into the dynamics of the asthma ...

Multivariate regular variation on cones: application to extreme values, hidden regular variation and conditioned limit laws [PDF]

open access: yesStochastics, 2008
We attempt to bring some modest unity to three subareas of heavy tail analysis and extreme value theory: limit laws for componentwise maxima of iid random variables;hidden regular variation and asymptotic independence;conditioned limit laws when one component of a random vector is extreme.

Quantitative Genetic Modeling of the Parental Care Hypothesis for the Evolution of Endothermy

open access: yesFrontiers in Physiology, 2017
There are two heuristic explanations proposed for the evolution of endothermy in vertebrates: a correlated response to selection for stable body temperatures, or as a correlated response to increased activity.

Simple models for multivariate regular variation and the Hüsler–Reiß Pareto distribution

open access: yesJournal of Multivariate Analysis, 2019
We revisit multivariate extreme value theory modeling by emphasizing multivariate regular variations and the multivariate Breiman Lemma. This allows us to recover in a simple framework the most popular multivariate extreme value distributions, such as the logistic, negative logistic, Dirichlet, extremal-$t$ and Hüsler-Reiss models.

Ligand‐dependent transcriptional heterogeneity in cell cycle gene expression delays G1/S entry

open access: yesFEBS Letters, EarlyView.
EGF and HRG induce distinct G1/S progression programs in ErbB2‐amplified BT474 breast cancer cells. Despite activating the potent ErbB2–ErbB3 heterodimer, HRG does not accelerate cell‐cycle entry. Instead, EGF promotes earlier restriction‐point passage via ERK–FOS signaling, whereas HRG activates the AKT–MYC axis, driving transcriptional heterogeneity ...
