Introduction to Biostatistics

16th March 2015

Tutorial on R: written by the trainer, this guides you through some of the concepts of data manipulation in R, followed by some descriptive statistics and a kind of pot-pourri of some of the things we are going to do with R this week.

An introduction to probability theory: also written by the trainer, may be a bit mathematical, but if you feel like doing some maths to reactivate this part of your brain that you will have to use throughout the week, you are most welcome! 🙂 We will go through some of this stuff during the first days of the week, we’ll see more on some aspects, and we will skip all the proofs (or almost all of them) during the lectures… If you want me to add more detail about this or that, please let me know during the week, it will be my pleasure to extend this.
