The aim of the course is to introduce basic theories and
methods of pure probability theory at an intermediate level. For example, the student will learn how to compute limits of sequences of stochastic variables by transform techniques. No knowledge of measure and integration theory is required, and only bare first statements of that will be included in the course. Techniques developed in this course are important
in statistical inference, statistical physics, time series analysis, financial analysis, signal processing, statistical mechanics, econometrics, and other branches of engineering and science. The course gives also a
background and tools required for studies of advanced courses in probability and statistics. The course is lectured and examined in English.
Prerequisites:
- SF 1901 or equivalent course a la 'a first course in probability and statistics (for engineers)'
- Basic differential and integral calculus, basic linear algebra.
- Previous knowledge of transform theory (e.g., Fourier transforms) and generating functions
is helpful, but not a necessary piece of prerequisites.
- The concept of Hilbert space will make an appearance, but is not actively required.

Course literature:
- T. Koski Lecture Notes: Probability and Random Processes Edition 2017 LN pdf
A hardcopy of this text can be bought at THS kårbokhandel (i.e., the bookstore at Campus Valhallavägen), address: Drottning Kristinas väg 19.
- The book by A. Gut An Intermediate Course in Probability, Springer-Verlag 1995 or later editions may be used for a secondary reading reference.
Important: Students, who are admitted to a course and who intend to attend it, need to activate themselves in Rapp . Log in there using your KTH-id and click on "activate" (aktivera).
The codename for sf2940 in Rapp is SF2940:sante16.
Examination:
There will be a written examination on Wednesday 25th of October, 2017, 08.00-
13.00. Allowed means of assistance for the exam are a calculator (but not the manual for it!) and the Appendix B of Gut, the Collection of Formulas and L. Råde & B. Westergren:
Mathematics Handbook for Science and Engineering.
Each student must bring her/his own calculator, Appendix B of Gut and the Collection of Formulas (that should be downloaded from this homepage) as well as the book by Råde & Westergren to the examination.
The department will NOT distribute the "Formulas and survey".
Grades are set according to the quality of the written examination.
Grades are given in the range A-F, where A is the best and F means
failed.
Fx means that you have the right to a complementary examination
(to reach the grade E).
The criteria for Fx is a grade F on the exam, and that an isolated part
of the course can be
identified where you have shown a particular lack of
knowledge and that the examination after a complementary examination on
this
part can be given the grade E.
The Re-exam is scheduled to take place on Tuesday December 19, 2017, 08.00-13.00.
Homework:
There will be two sets of elective homework assignments that will give bonus points in the written
exam on the 25th of October 2017, AND in the Re-exam 19th of December 2017. If you have received 5 bonus points you may skip Problem 1(a).
If you have received 10 bonus points you may skip the whole Problem 1.
Preliminary plan Exercises are from the Sections of Problems of LN. For example: Section 1.12.2 1 is the first exercise in section 1.12.2 in LN.
