Inhalt:

An introductory hands-on course that shows how to use R to analyze a typical psychophysical and social psychology research data. The course will walk you through all the analysis stages from importing a raw data to compiling a nice looking final report that automatically incorporates all the figures and statistics. If description below looks intimidating, do not despair! R wraps all these steps into simple easy-to-understand procedures. These include:

• data import, whether it is a CSV-file, Excel, SPSS, SAS, or Matlab and merging multiple data files into a single easy-to-use table (and saving it)
• data preprocessing: filtering out bad data and transforming values, e.g. turning continuous data into ordinal, degrees to radians, skewed data to a normally distributed ones, renaming and relabeling conditions, working with dates, etc.
• grouping and summarizing data: grouping data based on various combinations of conditions, computing group statistics or transforming data within each group
• plotting: R plotting package ggplot2 makes exploratory analysis easy and generates production-quality figures that you can use directly for your thesis or a publication
• statistical analysis: you will learn how to use various parametric (ANOVA, t-test, linear-mixed models) and non-parametric (traditional and permutation based) statistical tests, as well as the Bayesian approach to statistics and modern predictive modelling approaches (regression and classification using generalized linear models, linear discriminant analysis, support vector machines, etc.).
• putting it all together into a report: R helps you to automatically generate a nice looking report that includes all the analysis steps, figures, and statistics and export it for direct presentation (PDF, HTML) or for further editing (Word). Best part, if you change your mind and analysis, your final looking report is one button press away.

The best way to attend the course is with your own dataset. Bring it to the course and see how R will allow you to understand it deeper or reduce the time you need to analyze it. I am happy to help you all along with such statistical, methodological and graphical problems.

Statistical Rethinking [Statistical Rethinking]

Dozent/in:

Alexander Pastukhov

Angaben:

Sonstige Lehrveranstaltung, 2 SWS, ECTS: 3

Termine:

Mi, 14:00 - 16:00, M3N/03.28

Inhalt:

This is a book-club style seminar dedicated to reading and understanding "“Statistical Rethinking” book (online version with full text can be found here https://ebookcentral.proquest.com/lib/ub-bamberg/detail.action?docID=4648054).
It is an excellent introductory statistics book with a focus on Bayesian statistics, information criteria, and hierarchical models. It explains the principles slowly and clearly and has plenty of examples in R. Prior to each meeting everyone must read a chapter, do exercises. We meet to discuss the chapter and to help each other understand the tricky bits.
