Multivariable Regular Variation of Functions and Measures [PDF]
Journal of Applied Analysis, 1999 From authors' Introduction: ``A Borel measurable function \(R: \mathbb{R}^+\rightarrow\mathbb{R}^+\) is said to vary regularly at infinity with index \(\rho\in \mathbb{R}\) if, for all \(\lambda>0\) we have \(\lim R(\lambda t)/R(t)=\lambda^\rho\). \dots{} In this paper we establish some basic results on the geometry of regularly varying functions ...

Models with hidden regular variation: Generation and detection
Stochastic Systems, 2015 We review the notions of multivariate regular variation (MRV) and hidden regular variation (HRV) for distributions of random vectors and then discuss methods for generating models exhibiting both properties concentrating on the non-negative orthant in ...

Morpho‐Reproductive Stability of Rice Landraces Under Water Deficit Across Agroecological Zones of Far‐West Nepal [PDF]
Plant-Environment InteractionsRice landraces represent a reservoir of genetic diversity with potential for enhancing drought tolerance abilities. This study evaluated the morphological and reproductive responses of twelve rice landraces to drought stress from three agro‐ecological ...

Testing the Multivariate Regular Variation Model [PDF]
SSRN Electronic Journal, 2018 In this article, we propose a test for the multivariate regular variation (MRV) model. The test is based on testing whether the extreme value indices of the radial component conditional on the angular component falling in different subsets are the same.

Pareto Lévy Measures and Multivariate Regular Variation [PDF]
Advances in Applied Probability, 2012 We consider regular variation of a Lévy processX:= (Xt)t≥0inwith Lévy measure Π, emphasizing the dependence between jumps of its components. By transforming the one-dimensional marginal Lévy measures to those of a standard 1-stable Lévy process, we decouple the marginal Lévy measures from the dependence structure.
