Hello and Welcome at thebigdatablog.com. My name is Heiko Wagner and this Website is about stuff which is somewhat related to my research. However, this website has a different focus. While my research is mostly about theoretical properties of various estimators, this website is focussed on implementation details, in particular if we are facing a large amount of data. Beside I also want to present different projects I carried out in my spare time to a larger audience.
