Currently, the high-precision estimation of nonlinear parameters such as Gini indices, low-income proportions or other measures of inequality is particularly crucial. In the present paper, we propose a general class of estimators for such parameters that take into account univariate auxiliary...

The efficiency of the common law hypothesis has generated a large bulk of literature in the last decades. The main argument is that there is an implicit economic logic to the common law; the doctrines in common law provide a coherent and consistent system of incentives which induce efficient...

This work is motivated by the problem of defining non-linear PCA methods for the statistical analysis of densities. For this purpose, we introduce the method of Geodesic Principal Component Analysis (GPCA) analysis on the space of probability measures on the line, with finite second moments,...

After a brief review of support vector machines (SVM) classification, we will discuss the underlying optimization issues and available methods to perform training and propose new first order constrained approaches. The methods exploit the structure of the SVM training problem and combine ideas of...

This paper is an extended written version of the talk I delivered at the “XLe Journées de Statistique” in Ottawa, 2004, when being awarded the Marie-Jeanne Laurent-Duhamel prize. It is devoted to surveying some fundamental as well as some more recent results in the field of sequential prediction of...

Motivated by numerous applications, the statistical modeling of functional data received a lot of attention during the last years. However, procedures for functional regression model checks are only little developed. Consider a response variable taking values in a Hilbert space that admits a finite...

Concerns about rising inequality are making headlines all over the world, from America and Europe to China. Yet current debates and policy proposals focus on the recent past, neglecting the very long sweep of history and the lessons it may hold. This lecture traces the evolution of resource...
