Seminar stochastic geometry and its applications

Seminar Supervisor

Prof. Dr. Evgeny Spodarev
Prof. Dr. Volker Schmidt


Seminar Advisor

Stefan Roth


Date and Place

Time: Monday 2-4 pm, Place: Helmholtzstraße 22, E18


Prerequisites

The level of difficulty in this seminar is varying between the different topics. The audience is at least supposed to be familiar with basic probability and statistics. There are a few talks that require the lecture Stochastics II or beyond. We ensure the participants, that most of the 'beyond' knowledge will be learned during the seminar.


Intended Audience

Bachelor and Master Students of any mathematical study course.

The "(Bachelor)" in the list of talks, means that this talk is supposed to be given by a Bachelor's Student.


Content

Stein's Method: Central limit theorems for sums of independent random variables play a crucial role in statistics. Most of the classical proofs are based on Fourier analysis that give no ideas on the rates of convergence. It was Charles Stein who proposed a general method to estimate the approximation error in central limit theorems systematically. The idea of Stein's method and applications for different classes of limiting distributions will be given in this seminar. In this context we will see how to prove limit theorems for sums of dependent random variables as well as for stochastic processes.


Criterias to pass the seminar:

Each student is supposed to give a talk and to attend the seminar on a regular basis. Those who give a (good) talk and attend the seminar regularely will pass the seminar.
