Niels Bohr supposedly said if quantum mechanics did not make you dizzy then you did not really understand it. I think the same can be said about statistical inference.

News

  • "Klausureinsicht" on 14 February 2018 from 10:00am - 11:00am in INF 227 (KIP) / SR 3.404
  • Date of written exam: 5 February 2018 (2:15pm - 4:15pm), more details further below

Required knowledge

On the statistics side, there is no special knowledge is requires, and we will (briefly) repeat the basic principles of statistics. On the particle physics side, the PEP4 lecture is sufficient, and the lecture can serve as a natural follow-up of PEP4 for Bachelor students interested in Particle Physics. Master students are invited to attend this lecture in parallel or after the Particle Physics course. The tutorials will provide a step-by-step introduction to root and some basics of C++.

Practical information
