Uniform rates of the Glivenko-Cantelli convergence and their use in approximating Bayesian inferences

Seminar: Probability Seminar | August 22 | 3-4 p.m. | 1011 Evans Hall

Eugenio Regazzini, Universita degli Studi di Pavia, Italy

Department of Statistics

This talk deals with suitable quantifications in approximating a probability measure by an “empirical” random probability measure \hat p_n, depending on the first n terms of a sequence \{\xi_i\}_{i\ge1}
of random elements. In the first part, we study the range of oscillation near zero of the p-Wasserstein distance d(p) ....

Rerandomization and Regression Adjustment

Seminar: Neyman Seminar | August 22 | 4-5 p.m. | 1011 Evans Hall

Peng Ding, UC Berkeley

Department of Statistics

Randomization is a basis for the statistical inference of treatment effects without assumptions on the outcome generating process. Appropriately using covariates further yields more precise estimators in randomized experiments. In his seminal work Design of Experiments, R. A. Fisher suggested blocking on discrete covariates in the design stage and conducting the analysis of covariance (ANCOVA) in...   More >

Seminar 217, Risk Management: Is motor insurance ratemaking going to change with telematics and semi-autonomous vehicles?

Seminar: Risk Seminar | August 28 | 11 a.m.-12:30 p.m. | 1011 Evans Hall

Speaker: Montserrat Guillen, University of Barcelona

Consortium for Data Analytics in Risk

Many automobile insurance companies offer the possibility to monitor driving habits and distance driven by means of telematics devices installed in the vehicles. This provides a novel source of data that can be analysed to calculate personalised tariffs. For instance, drivers who accumulate a lot of miles should be charged more for their insurance coverage than those who make little use of their...   More >

Spectrum of random non-selfadjoint operators

Seminar: Probability Seminar | August 29 | 3-4 p.m. | 1011 Evans Hall

Martin Vogel, UC Berkeley

Department of Statistics

The spectrum of non-selfadjoint operators can be highly unstable even under very small perturbations. This phenomenon is referred to as "pseudospectral effect".
Traditionally this pseudosepctral effect was considered a drawback since it can be the source of immense numerical errors, as shown for instance in the works of L. N. Trefethen. However, this pseudospectral effect can also be the source...   More >
