All material will be consolidated in a booklet, which is available online.
Print copies will be provided as well on our first day of the prefresher.
Before arriving, we ask that you work through the pre-prefresher exercises on chapter 1 of the booklet, "Pre-Prefresher Exercises". The questions cover foundational concepts for the material in the prefresher, and we have provided links to the parts of the book you can read if the concepts are new to you. Incoming students come from a wide variety of backgrounds, so you are not expected to understand all of these before you arrive. However, if you have trouble we do encourage you to refer to the linked sections of the book to be able to attempt an answer for all questions.
The afternoons of the 2019 prefresher will be dedicated to programming and managing data. We ask participants to do the following before the first day of the prefresher.
Make a Rstudio Cloud account at https://rstudio.cloud/ and work through two of their “primers” - interactive tutorials. If you have a "@g.havard.edu" email account, you can “Sign in by Gmail” because g.harvard.edu is a G-Suite domain. We will be using Rstudio Cloud for the programming portion of the course. Moreover, the interactive tutorials will help you familiarize yourself with basic programming concepts and R.
Also, 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 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)
