Course description and aims

This course gives a standard introduction to mathematical statistics. In the estimation theory, starting from linear regression, the methodologies and properties of estimators such as the maximal likelihood estimator and the Bayes estimator will be explained. Following the estimation theory, the test theory will be taught. In the test theory, several tests such as two sample test, independence test, and analysis of variance will be explained. Throughout the course, optimalities of the estimation methods and the tests will be discussed based on the statistical decision theory.

Student learning outcomes

Statistics is a methodology to deduce useful knowledge from data to help decision making. Through this course, the students should learn the basics of the mathematical statistics and several methods of statistics. Finally, it is expected that the students will be able to use the statistical methods. It is also expected that by learning statistics, the students will learn knowledge that is also useful for other fields such as machine learning and signal processing.

Keywords

mathematical statistics, linear regression, maximum likelihood estimator, Bayes estimator, unbiased estimator, Cramer-Rao inequality, Fisher information, asymptotics, decision theory, test, two sample test, independence test, analysis of variance, confidence interval

Competencies that will be developed

Specialist skills Intercultural skills Communication skills Critical thinking skills Practical and/or problem-solving skills

Class flow

The course consists of lecture and exercise. In the lecture, the contents will be explained mainly using a black board. In the exercise, the students should solve problems and submit reports.
