Stochastic Processes at CEU -- winter semester 2013/14

HOMEWORKS here.

No. of Credits: 3
No. of ECTS credits: 6
Time Period of the course: Winter Semester
Prerequisites: Probability 1
Course Level: PhD
Syllabus: will be here.
Classes: Wednesdays from 12:00 in room 301.
Course Coordinator: Imre Péter Tóth.

THE FINAL EXAM will be an oral exam on Thursday, the 24th of April 2014, starting at 9:00. LIST OF QUESTIONS HERE.

Topics actually covered: Suggested literature (References):
  1. Specific chapters to some of the lectures:
  2. General:
Grading rules:
There will be three homework assignments -- roughly once in every four weeks -- worth 20% of the total score. A midterm exam focused on problem solving will be worth 30%, while the final exam, focused on theory will be worth 50%.

Requirements for "audit":
regular participation in class and a short oral account of the concepts and phenomena learned.

Just for the record: Planned schedule, far from what was actually covered:
