Course Literature

Lecture notes available here (pdf)

Course material:

G. Cowan: Statistical Data Analysis(Oxford University Press 1998)

- A comprehensive reference of Statistical Methods in Physics. Contains both theoretical background and practical examples. Highly recommended.

Particle Data Group Reviews on Probability, Statistics & Monte Carlo techniques(freely available on the web)

- Good but rather condensed summaries. Written by the same author,G. Cowan.

C. Walck: Hand-book on statistical distributions for experimentalists(freely available on the web)

- An opus on statistical distributions. When knowing your physics distribution, useful for finding out distribution characteristics and generation.

Course Content

The course should provide the student a firm basis to statistically correctly analyze data from an physics experiment and do a valid interpretation of the result.

Fundamental concepts:experimental errors and their correct interpretation, frequentist & Bayesian interpretation of probability, the most common distributions and their applications.Monte Carlo methods & statistical tests:basics of Monte Carlo methods, the concepts of a hypothesis, a test statistic and the basic principles for the rejection of a hypothesis.Parameter & error estimation:the concept of estimation, the maximum likelihood method (suurimman uskottavuuden menetelmä) and the method of least squares (pienimmän neliösumman menetelmä).Confidence intervals & Unfolding

Course Grading (for autumn 2017)

Exercises (10 papers) gives at maximum 36 points (weight: 50 %),

Home exam gives at maximum 36 points (weight: 50 %),

Written exam gives at maximum 36 points (weight: 50 %).

The two best of these three will be used for making the course grade

(you may choose to do only one out of the two exams if you wish).
