Lecture material will be posted on the Moodle class web page.
Lecture notes on R are freely available on the website https://cran.r-project.org/.
Information on manuals that use R for statistical analysis will be provided during the lab sessions.
Learning Objectives
The objective of the course is to provide basic knowledge and skills on the statistical analysis of data using the R software. The lab sessions aim to apply the methods presented in the previous statistical courses and to highlight the operational problems connected with applications on real data.
The objectives of knowledge and understanding and ability to apply knowledge and understanding are the following.
Knowledge and understanding: Know and understand the operational basics of the software R.
Application of knowledge and understanding: The student must be able to autonomously apply the statistical analysis procedures presented and to interpret the results, paying particular attention to the nature and reliability of the data analyzed and to the potential and limitations of the models and methods used.
Prerequisites
It is assumed that students are familiar with basic descriptive and inferential statistics. Furthermore, knowledge of the statistical methods provided in the “Introduction to Econometrics” and “Economic Statistics” courses is required.
Teaching Methods
Lab sessions. Attendance of the course is mandatory.
