Statistical skills

I'm co-chairing the working group "Methods" of the German Society of Medical Sociology (AG Methoden / DGMS) and do a lot R programminh. Currently, I'm mostly involved in projects related to R statistics (through the easystats project or my other packages like ggeffects). However, my previous main activity in developing research software was the Zettelkasten, in Java.

Here are the main R-package projects I'm working on:


  • report: 📜 🎉 Automated reporting of objects in R
  • bayestestR: 👻 Utilities for analyzing Bayesian models and posterior distributions
  • correlation: 🔗 Methods for Correlation Analysis
  • modelbased: 📈 Estimate effects, contrasts and means based on statistical models
  • effectsize: 🐉 Compute and work with indices of effect size and standardized parameters
  • parameters: 📊 Computation and processing of models' parameters
  • performance: 💪 Models' quality and performance metrics (R2, ICC, LOO, AIC, BF, ...)
  • insight: 🔮 Easy access to model information for various model objects

Data Visualization

  • ggeffects: Estimated marginal means and effects plots for regression models
  • sjPlot: Plots and tables for summary statistics, descriptive statistics and regression models
  • see: 🎨 Visualisation toolbox for beautiful and publication-ready figures
