Teaching results
The aim of the course is to teach students the knowledge and skills related to modern methods of applied data analysis and statistical learning, including the use of R software, for conducting empirical economic research and designing research methods to solve economic problems.
Upon completion of the course, students should acquire:
a) knowledge of modern methods of research and data visualization, linear regression, general data analysis, and statistical learning.
b) skills in working with data that they can use in their own empirical research. Additionally, they will acquire advanced skills in using modern software (R) for empirical economic research, be able to write their own functions, use functions for data visualization, and empirically estimate advanced methods of statistical learning.
c) competences to design research for a given economic problem and perform data analysis. They will be competent to further develop their knowledge in data analysis and the use of modern software, understand empirical articles from applied data analysis, and be able to apply them in new contexts.
