The case-crossover design via penalized regression

In this episode I talk to Sam Doerken.  Sam is a mathematician by training, having studied mathematics at the  University of Heidelberg. He did his diploma thesis in mathematics on Probabilistic Forecasting of U.S. Treasury Bills . Since 2012 he works at the  Institute of Medical Biometry and Statistics at the University of Freiburg.

In this part we cover the paper "The case-crossover design via penalized regression" , published in BMC Medical Research Methodology. The authors conclude that "for the case-crossover design, we also encourage penalized regression for routine use."
