- 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.
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).
Exercises given latest on Fridays, notification by e-mail, to be returned following Thursday before 12.00 Finnish time.
Exercise papers available here (pdf).
To be returned either to the locked box (rightmost row, 2nd from bottom) at Physicum's 2nd floor or by e-mail to fredrik.oljemark(at)helsinki.fi
