Course Syllabus


The course will provide underlying principles of mathematical statistics for statistical inference in the field of economics and sociology. This course will be focused on the methods of statistical inference including parameter estimation and hypothesis testing. Further results of the course can be used for the specialization courses in statistics and econometrics.
Learning Objectives

Learning Objectives

  • The goal of this course is to broaden and systematize students’ knowledge of econometrics and to practice its application. During the course we will go through the essentials of econometrics: from the statistical background through the theory and intuition behind regression analysis to practical applications. The course is elementary and presents concepts and techniques in way that benefits students of all mathematical backgrounds. Fundamental concepts and methods of statistics and econometrics are introduced with emphasis on interpretation of arguments and application to real-world problems. Every topic will be backed up with an applied exercise.

Assessment Elements

Assessment Elements

  • non-blocking Homework Assignments
    Late homework submission WILL NOT BE ACCEPTED. - Students are allowed to work on homework assignments individually or in groups of two. - Homework outputs will be handed in a printed version at the beginning of a predefined class (unless agreed differently). If the students work in pairs, the role of each student needs to be described and both students need to sign it (there will be 50% point deduction it is missing).
  • non-blocking Project
    - At the beginning of the course each student will be given a dataset. Student will use the dataset throughout the course. The dataset will be also used in the final project, whose main goal is to provide students with practical exercise of what will be taught during the course and to apply knowledge using statistical softwares (MS Office, and GRETL/SPSS/STATA). - Student will work on the project individually. - Project accounts for 15 per cent of the final grade and need to be handed at the end of the semester (the date will be agreed during the class). - Projects will be presented during the last lecture.
  • non-blocking Quizzes
    - No retakes are allowed for quizzes. - Quizzes will NOT be announced in advance.
  • non-blocking Exam 1
    - Retake of exam 1 is allowed only if the student was sick and has a confirmation from a doctor. - ONLY BASIC CALCULATORS will be allowed in the exams. - EXAM 1 is an open-book exam, i.e., you can use all your HANDWRITTEN materials (exception: printed lecture notes).
  • non-blocking Exam 2
    - The exam retake policy is: A student can retake exam 2 if her/his score was below 50%. - ONLY BASIC CALCULATORS will be allowed in the exams. - EXAM 2 is a closed-book exam.
