Categorical Data Analysis, autumn 2015 (78179)

Lecturer: Pekka Pere

Scope: 5 cr

Type: Intermediate studies. The course can be updated to advanced studies by conducting a statistical analysis of real data and writing a careful report of the analysis.

Prerequisities: Statistical inference II. Linear models I is recommendable (the associated matrix algebra is not utilised).

Description: Likelihood based methods for analysis of categorical data are explored. These include confidence intervals and tests for proportions and differences of them, testing for independence, small sample adjustments and methods and logistic regression. McNemar’s test for matched pairs data is also presented. R software is used in homework assignments.

Aspiration: Theory of statistical inference becomes alive in students’ minds in the context of categorical data. Students become aware of potential exciting applications, develop a skill to do them themselves and a desire to learn more.

Exercises:

Working out of exercises is rewarded as extra points in the grading of the final examination (details to be explained at the first lecture). Exercises can be solved in groups. An exercise can be marked completed if it appears correct to you and you are ready to present it at the exercises. The rewarded points apply if the student has reached the minimum points from the final examination for passing the course (half of the total points).
