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...

This paper explains the adoption of different electoral rules by legal systems. I argue that common law system is intended to protect an individualistic constitution, while civil law system aims at facilitating a more active government. I model the choice of electoral system as a choice of the...

I analyze a Gaussian linear instrumental variables model with a single endogenous regressor in which the number of instruments is large. I use an invariance property of the model and a Bernstein-von Mises type argument to construct an integrated likelihood which by design yields inference...
