Computing

The default computing language for this course is R, is free (as in speech) and available from CRAN. Other languages (e.g. python, MATLAB, STATA, ...) are allowed. Examples in lecture, homework solutions, etc., will be in R.

Get started before class starts!

• A good introduction/tutorial to R is here.
• UCLA has a fantastic help page for R (and statistics/regression in general) with everything from installation/basic help, worked-through examples, books, and link to more resources.
• The University offers R workshops in the Research Computing Center, see schedule here and has e-books available here.
• The resources out there are continually changing, so you may find other options. Please let me know if you find something helpful that isn't listed here.
