Willem M. Van der Wal, PhD

I'm Willem van der Wal. I have a PhD in Biostatistics and work as a statistical researcher in The Netherlands. In my spare time I conduct research in fields that I find fascinating such as policy analysis and criminology. The work that I (will) present on this site is conducted by me as a private individual, and is not endorsed or supported by any organization. Opinions expressed are solely my own. Furthermore, since I'm employed as a civil servant in The Netherlands, I will refrain from commenting on the situation in my country. In stead, I will focus mainly on the USA which I have a fascination for.

New: I wrote a tutorial on how to prepare a dataset for inverse probability of censoring weighting (IPCW) with my R package ipw ipw. You can find it at my blog.
