Course objectives
The goal of this course is to provide students with practical tools for preparing, analyzing, and visualizing economic data.


Students can use the acquired skills while working on their theses and in commercial practice, particularly in analyzing financial markets, international trade, market organizations, migration, transport economics, competition, microeconomics, macroeconomics, and other tasks. The course will also lay the foundation for further study and application of advanced statistical methods, econometrics, data mining, and data science.


Emphasis is placed on the practical mastery of the tools mostly used to analyze economic data.


Examples of the use of tools can be seen at https://aved.econ.muni.cz/appetizer.html.



Classes will be held in R language. R is the world's most widely used statistical data analysis tool, which lets you apply all statistical, econometric, data-mining-and other methods without additional auxiliary software (such as Excel, Gretl, Statistica, SPSS, etc.). R is used in both academia and commercial practice. It is used by companies such as Google, Facebook, and Microsoft. R can be downloaded free of charge for all operating systems at https://cran.r-project.org/.



Most of the necessary literature (including the required one) is available legally online.

Learning outcomes
Completing the course, students will gain the following skills:

  • They will be able to retrieve data in almost any format and structure from local resources and online databases, clean it, and convert it into a convenient structure that allows easy analysis.
  • They will be able to handle large volumes of data: to transform them, aggregate them, and combine different data sets.
  • They will be able to detect errors in data sets systematically.
  • They will be able to visualize individual data of various types and relationships between them in an advanced way.
  • They will be able to carry out an initial exploratory data analysis and subsequent statistical and econometric analysis.
  • They will be able to handle their projects so that they can be replicated and updated automatically, for example, if they get new data.
    • Syllabus
    • Introduction to R: installation, startup, and shutdown of R, installation, use of libraries, help, vignettes, development environment (RStudio), writing and running scripts.
    • Data and variables: assigning data to variables; datatypes, coercion; arithmetic operations; loading and saving data.
    • Information about data: attributes, subsets, factors, dates, objects, and their classes.
    • Automatic Data Processing 1: function calls, basic mathematical and statistical functions, and tests.
    • Automatic Data Processing 2: custom functions, functionals; sequences, sampling, and set operations.
    • Automatic Data Processing 3: Working with strings -- regular expressions, transformations of strings, and retrieving data from strings.
    • Automatic Data Processing 4: Well formatted data -- well-formatted data structure and data conversion in a well-formatted data.
    • Automatic Data Processing 5: transformations, selections from data, data aggregation, linking information from different data sets.
    • Data Visualization 1: Grammar of graphs and visualization of univariate data.
    • Data Visualization 2: Visualizing relationships in data.
    • Introduction to Econometrics in R.
    • Exploratory data analysis (EDA).
    • Reproducible research: producing concise and maintainable data structures and code, creating automatically generated documents that contain text and outputs of data analysis (when there are 13 weeks in the semester).

    Teaching methods
    AVED consists of home preparation and tutorials. Students are assumed to watch video lectures and read lecture notes at home. Tutorials are held in a computer lab. They are devoted to applying acquired skills to real or stylized data sets.
    Assessment methods
    The course is evaluated based on attendance (10%), in-class tests (10%), homework (40%), and a final practical exam (40 %). Homework and final practical exam include preparation, analysis, and visualization of given data. Completing the course requires obtaining at least 50% of the points from the final exam and 50% of the total possible points.


    Homework is to be submitted on an ongoing basis in the form of code.


    During the exam, you can use all the materials available in the development environment, the course study materials, and your notes. Communication with living people and access to the Internet is prohibited.



    It is also possible to enroll in the course while studying abroad (e.g., Erasmus). The student will prepare homework during the semester and will write the final test after returning from abroad. Please get in touch with the teachers before departure.



    Any copying, recording, or taking out the tests, use of unauthorized devices and means of communication, or other distortions in the objectivity test (credit) will be considered a failure to meet the   course completion and a gross violation of study regulations. Consequently, the teacher closes the test (credit) score in   IS grade "F," and the Dean initiates disciplinary proceedings, which may result in up to graduation.
