My name is Hansjörg Plieninger, I am a postdoctoral researcher in the psychology department at the University of Mannheim, Germany. I love data science and I love R. From an academic perspective, I am an expert in psychometrics, item response theory, structural equation modeling, and multilevel modeling; more specifically, I use this machinery to investigate response styles (e.g., tendency to give extreme responses). From a data-science perspective, I am an expert in dealing with survey data, Likert-type data and the like.
This blog is about …
- things I learned, to make it simpler for other people to learn the same thing quicker,
- things I learned, to make it simpler for me to do the same thing quicker next time,
- things I love, to make it simpler for others to love them, too,
- things I do, to make it simpler for you to get in touch with me.
And the motto of this blog comes from one of my favorite R packages, fortunes:
fortunes::fortune("done it.") #> #> It was simple, but you know, it's always simple when you've done it. #> -- Simone Gabbriellini (after solving a problem with a trick suggested #> on the list) #> R-help (August 2005)
