Introduction to Statistical Programming with R

Introduction to Statistical Programming with R

Brief summary of the course

In this course, we consider the features of the programming language R with an emphasis on functions designed for statistical analysis and modeling. This course will make it easier for you to study econometrics, as R allows you to do statistical data analysis with a minimum of writing your own code.

Learning outcomes

By the end of the course students will have specialized conceptual knowledge that includes modern scientific achievements in the field of computer science and is the basis for original thinking and research, critical thinking of problems in the field of computer science and on the verge of knowledge fields; develop algorithmic and software for data analysis (including big data); design architectural solutions for information and computer systems for various purposes; test the software; identify and eliminate issues during software exploitations, and formulate tasks for its modification or reengineering.
