Modelling dependence within joint tail regions

AW Ledford, JA Tawn - Journal of the Royal Statistical Society …, 1997 - Wiley Online Library
Standard approaches for modelling dependence within joint tail regions are based on extreme
value methods which assume max‐stability, a particular form of joint tail dependence. We …

Prostaglandin synthase 2 gene disruption causes severe renal pathology in the mouse

…, JC Jennette, JF Mahler, KD Kluckman, A Ledford… - Cell, 1995 - cell.com
The prostaglandin endoperoxide H synthase isoform 2, cyclooxygenase 2 (COX-2), is induced
at high levels in migratory and other responding cells by proinflammatory stimuli. COX-2 …

Statistics for near independence in multivariate extreme values

AW Ledford, JA Tawn - Biometrika, 1996 - academic.oup.com
We propose a multivariate extreme value threshold model for joint tail estimation which
overcomes the problems encountered with existing techniques when the variables are near …

Evolution and mechanism of apolipoprotein B-containing lipoprotein assembly

GS Shelness, AS Ledford - Current opinion in lipidology, 2005 - journals.lww.com
The phylogenic dissection of MTP and apolipoprotein B function, coupled with ongoing
structural and biochemical analyses, provide significant insights into the mechanisms of lipid …

Diagnostics for dependence within time series extremes

AW Ledford, JA Tawn - Journal of the Royal Statistical Society …, 2003 - academic.oup.com
The analysis of extreme values within a stationary time series entails various assumptions
concerning its long- and short-range dependence. We present a range of new diagnostic tools …

Dynamic modelling and prediction of English Football League matches for betting

M Crowder, M Dixon, A Ledford… - Journal of the Royal …, 2002 - academic.oup.com
We focus on modelling the 92 soccer teams in the English Football Association League over

Concomitant tail behaviour for extremes

AW Ledford, JA Tawn - Advances in applied Probability, 1998 - cambridge.org
The influence of bivariate extremal dependence on the limiting behaviour of the concomitant
of the largest order statistic is examined. Our approach is to fix the marginal distributions …

Kombucha, the fermented tea: microbiology, composition, and claimed health effects

CJ Greenwalt, KH Steinkraus, RA Ledford - Journal of food protection, 2000 - Elsevier
Kombucha is a slightly sweet, slightly acidic tea beverage consumed worldwide, but historically
in China, Russia, and Germany. Kombucha is prepared by fermenting sweetened black …

[HTML][HTML] Extinction coefficients of NO2 and N2O4

AM Bass, AE Ledford Jr, AH Laufer - Journal of Research of the …, 1976 - ncbi.nlm.nih.gov
The extinction coefficient of NO 2 has been measured in the spectral range 185 to 410 nm
as a function of temperature between 235 and 298 K. In order to correct for the effect of the …

Psychological and physiological predictors of resilience in Navy SEAL training
