The exam from November 2 2018 is found here with short solutions.
The reexam is Monday January 7 8.00-13.00 at Victoriastadion Vic:2C-D. Registration is mandatory.
The exam is corrected and can be viewed Monday November 26 12.30-13.00 in MH:227.
More typos by a confused 'tryckfelsnisse'. Please check the solution of 5c in old exam 171028.
Some smaller errors can be found in the solutions of old exam 170817 5b (a typo not changing the answer) and 6b (the answer is changed). The corrected solutions are found below.
The course is concluded with a written exam, Friday November 2, 14.00-19.00, at Victoriastadion, Vic:2 and 3A.
The exam will be in english. You are allowed to bring a pocket calculator and the table of formulas of this course. You can also bring some small 'high school' table of formulas in mathematics (e.g. TEFYMA). Table of formulas must not contain any marks or comments.

The computer exercises require basic knowledge of Matlab. If you have not used Matlab, prepare by writing simple command lines and collect them in a script. The extra files for the exercises are found here.
Course contents
Stochastic processes find applications in a wide variety of fields and offer a refined and powerful framework to examine and analyse time series. This course presents the basics for the treatment of stochastic signals and time series. For a stochastic process to be stationary, the mechanism of the generation of the data should not change with time. Mathematical tools for processing of such data is covariance and spectral analysis, where different models could be used. Some usual models are autoregressive (AR) and moving average (MA) processes. For appropriate modelling, we need reliable estimation of covariance functions and spectral densities. Linear filtering, differentiation and integration of stationary stochastic processes are other important parts of this course.
