Autor: Anne Gégout Petit, Hélène Jeulin, Karine Legrand, Nicolas Jay, Agathe Bochnakian, Pierre Vallois, Evelyne Schvoerer, Francis Guillemin

Publikováno v: Viruses, Vol 13, Iss 6, p 1076 (2021)

The World Health Organisation recommends monitoring the circulation of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). We investigated anti–SARS-CoV-2 total immunoglobulin (IgT) antibody seroprevalence and in vitro sero-neutralization

Graph estimation for Gaussian data zero-inflated by double truncation

Autor: Anne, Gégout-Petit, Aurélie, Gueudin-Muller, Clémence, Karmann

We consider the problem of graph estimation in a zero-inflated Gaussian model. In this model, zero-inflation is obtained by double truncation (right and left) of a Gaussian vector. The goal is to recover the latent graph structure of the Gaussian vec

Report

Optimal quantization applied to Sliced Inverse Regression

Autor: Romain, Azaïs, Anne, Gégout-Petit, Jérôme, Saracco

In this paper we consider a semiparametric regression model involving a $d$-dimensional quantitative explanatory variable $X$ and including a dimension reduction of $X$ via an index $\beta'X$. In this model, the main goal is to estimate the euclidean

Annals of Forest Science, 2022, 79 (1), pp.23. ⟨10.1186/s13595-022-01142-y⟩

Key message An influence of the recent changes in temperature or rainfall was demonstrated, increasing background tree mortality rates for 2/3 of the 12 studied tree species. Climate change-induced tree mortality was exacerbated towards the warm or d

International audience; We propose a new methodology for selecting and ranking covariates associated with a variable of interest in a context of high-dimensional data under dependence but few observations. The methodology successively intertwines the

International audience; Sequential detection is based on a recursive statistic and a threshold it must reach to report a change. In this paper, we consider the score-based CUSUM statistic and propose to evaluate the detection performance of some thre

Climate change impact on tree mortality differs with tree social status

Statistical analysis of grapevine mortality associated with esca or Eutypa dieback foliar expression

Autor: Lucia GUERIN-DUBRANA, Amaury LABENNE, Jean Christophe LABROUSSE, Sylvie BASTIEN, Patrice REY, Anne GÉGOUT-PETIT

Publikováno v: Phytopathologia Mediterranea, Vol 52, Iss 2 (2012)

Esca and Eutypa dieback are two major wood diseases of grapevine in France. Their widespread distribution in vineyards leads to vine decline and to a loss in productivity. However, little is known either about the temporal dynamics of these diseases
