Statistical estimation with model selection Lucien

The purpose of this paper is to explain the interest and importance of (approximate) models and model selection in Statistics. Starting from the very elementary example of histograms we present a general notion of finite dimensional model for statistical estimation and we explain what type of risk bounds can be expected from the use of one such model. We then give the performance of suitable mo...

Se p 20 06 Model selection for Poisson processes Lucien

Our purpose in this paper is to apply the general methodology for model selection based on T-estimators developed in Birgé (2006a) to the particular situation of the estimation of the unknown mean measure of a Poisson process. We introduce a Hellinger type distance between finite positive measures to serve as our loss function and we build suitable tests between balls (with respect to this dist...

Lucien Howe, hereditary blindness, and the eugenics movement.

Ophthalmologists admire Lucien Howe, MD (1848-1928) (Figure 1), for his leadership and philanthropy. During his presidency of the American Ophthalmological Society (AOS), the organization established an award for contributions to ophthalmology, now known as the Howe Medal (Figure 2), one of the highest honors in the specialty. In addition, there are 2 other Howe Medals and a Howe Award, each of...
