Biostatistics, statistical epidemiology and more

Medical scientific knowledge can be developed only with careful consideration of the uncertainty in made research findings, because medical experiments and observations provide at best fragmentary and imperfect information. Statistics is the scientific methodology for extending the conclusions from such observations beyond the observed data.

This is the personal website of Jonas Ranstam, a medical statistician with experience from academic medical research as well as from research and development in the drug and device industry. It includes CV, publications list, presentations from recent lectures, and computer scripts for statistical calculation. It also has a blog with comments on statistical issues and suggestions on how to solve some software and hardware problems.

In addition, the website provides facilities for making appointments, transferring files securely, and for statistical computing. A server for distributed computing, the R-server, executes programs on demand using the software environment R. The server currently has routines for sample size calculation, randomization list development, hypothesis testing, confidence interval estimation, and quality control.
