Särskild behörighet Biostatistics I: Introduction for epidemiologists or corresponding courses.
Kursens syfte The purpose of this course is to introduce students to using the R statistical software to perform basic to intermediate statistical data analysis in a replicable manner.
Kursens lärandemål After successfully completing this course, students are expected to be able to:
- explain basic concepts of the R language and environment, the online- and offline sources of documentation for R, and basic concepts of data management and workflow in a standard statistical analysis,
- run a standard statistical analysis interactively within the R environment,
- formalize and document such a standard analysis as a stand-alone R script,
- produce graphical representations, as part of reporting their analysis,
- interpret their scripts for potential simplifications via functional implementation,
- find, install and compare extension packages for unfamiliar statistical applications.
Kursens innehåll The course will cover the basic elements of a standard statistical workflow: reading data into R; pre-processing and quality assessment of data via numerical and graphical methods; descriptive statistics via summary measures, tabulations and graphics; basic statistical inference in terms of significance testing and confidence intervals; specification, fitting & diagnosis of regression models; exporting and reporting results from the previous steps. The course includes an introduction to the Rstudio integrated development environment to provide a common framework for interactive and scripted analysis. The extensibility of the R system will be demonstrated by example.
Arbetsformer Course days will be organized around a common theme, with concepts and background covered in the mornings via presentations, demos, in-class exercises and discussions, and practical application via individual and small-group lab exercises in the afternoons. Formative assessment will be integrated via in-class quizzes and lab reviews.
Obligatoriska moment The individual examination (summative assessment) is compulsory.
Examination Students will perform an open-book examination based on practical application of the concepts presented during the course to realistic data sets and problems. Students who do not pass the examination will be offered a second examination within two months from the end of the course (excluding academic holidays).
