Booklet
All material will be consolidated in a booklet, which is will be available online shortly. If you'd like extra practice, we strongly suggest reviewing the booklet from last year's prefresher, available here.
Math Preparation
Before arriving, we ask that you work through the pre-prefresher exercises on chapter 1 of the booklet. Incoming students come from a wide variety of backgrounds, so you are not expected to understand all of these before you arrive.
Programming Preparation
The afternoons of the 2023 prefresher will be dedicated to programming and managing data. We ask participants to do the following before the first day of the prefresher.
Secure a laptop and charger you can use throughout the prefresher. If you do not have one at the moment, we can arrange to have you borrow a laptop from IQSS. Please contact the instructors.
Through the following links, install these three Applications on your laptop (either Windows or Mac), if you do not have them already.
- R (at least version 4.2.0)
- RStudio Desktop Open Source License.
-
LaTeX: We will use the TinyTeX LaTeX distribution. It is designed for R users, which you will soon consider yourself if you don't already. Once you have R installed, simply run the following two lines:
- install.packages('tinytex')
- tinytex::install_tinytex()
R is the statistical program we will concentrate on in the prefresher. RStudio is a graphical user interface (GUI) that makes it easier for users to use R. Separately, TeX is a typesetting software. All are free of charge.
If you do have R and/or RStudio on your laptop already, please try to update both of them to their newest version (Search "Check for updates" in Help)
