About me:
My
PhD thesis 'Categorical Data Analysis
Reordered' focussed on reordering and
clustering techniques for nominal data
as well as methods for visualization.
Further interests: Large
datasets, interactive visual data
analysis, conditional graphics, statistical
modeling, classification and clustering
techniques, dimension reduction
techniques and graph theory
Some of the methodologies I developed for my
PhD are available in my R-package:
extracat
