Daniel Schalk

Statistician / Data Scientist

Personal Profile

I am statistician, aka data scientist, with strong interests in machine learning, statistical modelling, programming, automated reporting, and data visualization. Besides the theoreical aspects, which I find very important, I am also interested in the practical applications of machine learning. Therefore, I am author of an model-based boosting package called compboost written in C++ and R.
