Analysis of Epidemiological Data: Wednesday 23, Thursday 24

**Lectures:****Practical exercises**- The exercises in this course requires you to do calculations which
in principle can be done on a hand-calculator.

However we assume that you use your laptop and use the free statistical programas a calculator. This will enable you to take the solutions with you home in the form of a file with computer code that does the analyses. It will also enable you to do analyses repeatedly on slightly different sets of data.`R` - You can obtain
from CRAN (the`R`omprehensive`C``R`rchive`A`etwork): Under`N``"Download and Install R"`click on`"R for Windows"`, click on`"Install R for the first time"`, and then on`"Download R 3.4.1 for Windows"`, which is a self-extracting installer (about 62MB). This means that if you save it to your computer somewhere and click on it, it will installfor you (provided that you answer the questions you are asked).`R` - The
`Epi`add-on package forwill be needed too. Once you have installed`R`, start it, and in the menu bar click on`R``Packages -> Install package(s)...`, chose a mirror (this is just a server where you can get the stuff), and then the`Epi`package. Startand write:`R`

`> library(Epi)`

`> sessionInfo()`

- from the output of the last command it should be clear that you have version 2.16 of the`Epi`package. -
**Practical Exercises Workbook**contains the exercises that you will go through during the practicals sessions in the two modules "Measures of disease frequency and effects" and "Analysis of Epidemiological Data".

It also contains a very short introduction to getting and using, and a section with basic probability concepts in epidemiology and demography.`R` **An introduction to R for Epidemiology**may be of interest for you (about 50 pages).- Here are the
**R-code files**corresponding to the solutions in the workbook.

- The exercises in this course requires you to do calculations which
in principle can be done on a hand-calculator.
**NORDCAN**is an interactive database where you can get information on cancer occurrence in the Nordic countries. It will also be used during the exercises.**After the course**
