On maximum likelihood estimation of the extreme value index (2004)
Drees, Holger, Ferreira, Ana, De Haan, Laurens
We prove asymptotic normality of the so-called maximum likelihood estimator of the extreme value index.

Bivariate tail estimation: dependence in asymptotic independence (2004)
Draisma, Gerrit, Drees, Holger, Ferreira, Ana, De Haan, Laurens
In the classical setting of bivariate extreme value theory, the procedures for estimating the probability of an extreme event are not applicable if the componentwise maxima of the observations are...

In sporadic colorectal tumours the BRAFV600E is associated with microsatellite instability (MSI-H) and inversely associated to KRAS mutations. Tumours from HNPCC patients carrying germline mutations...

Optimal Confidence Intervals for the Tail Index and High Quantiles
The aim of the paper is to obtain confidence intervals for the tail index and high quantiles taking into account the optimal rate of convergence of the estimator. The common approach to obtaining...
Heme oxygenase-1 affords protection against noncerebral forms of severe malaria
Seixas, Elsa, Gozzelino, Raffaella, Chora, Ângelo, Ferreira, Ana, Silva, Gabriela, Larsen, Rasmus, ...
Infection by Plasmodium, the causative agent of malaria, is associated with hemolysis and therefore with release of hemoglobin from RBC. Under inflammatory conditions, cell-free hemoglobin can be...
