Research

The Chair for Psychological Methods, Evaluation, and Statistics conducts methodological research at the intersection of statistics, psychometrics, and machine learning. 

For example, we develop methods for detecting parameter differences in psychometric models, as these can violate the fairness of psychological tests. Some of these methods are based on classical, parametric statistics, while others draw on approaches from machine learning.

In the area of machine learning, we develop methods for assessing stability and for reliably measuring and interpreting the contributions of predictor variables. These topics are also relevant to some of our work in psychometric computing.

Across all research areas we contribute to the development of add-on packages for the free, open-source software R. These R packages are listed below.
