Mathematical statistics

We are all in this together!!

... As a statistician, one thing I've learned to use while brainstorming on a problem is the hive-mind. :) So, if you ever feel completely stuck on a problem, try to rely on the collective wisdom! You are not alone. It is extremely common to get `stuck' when thinking about a new concept (such as an algebraic variety!?) - so, ask your classmates, not only your professor! Visit the course Campuswire page to throw out a half-baked idea, start an example and pose a question `now what?'. Let yourself be surprised by how creative you are, as a collective!

Afraid? Shy? Unsure? No problem: you may post questions anonymously!

Inspired? Motivated? Post an answer to someone else's question! (And earn participation points while doing it.)

Help with writing up assignments

To improve your analytical writing quickly, start by writing draft solutions to homework early. A day or two later after you have had time to forget what you wrote, read it. If it doesn’t make sense or convince you, rewrite it. Writing a solution requires saying what you mean and meaning what you say. Be intellectually honest. Intellectual dishonesty includes: 1) stating a “reason” without understanding its relevance. 2) Claiming a conclusion when you know you haven’t proved it. 3) Giving an example and claiming you have proved the statement for all instances.

Software & Statistics help

New to R? Can't remember something "basic" in stats? Just need a refresher?

Not to worry!
Writing scripts: One of our reference texts has a lot of background and examples - it builds scripts bottom-up! You can always start there. If you want to browse a few other resources, these seem excellent choices:

  • A site with various tutorials on R and statistics

  • Learn R in 15 minutes from Prof. Yang at UIC (visit this page with so many more links, too!)

  • RMarkdown cheatsheet

Stats refreshers:

  • Video lectures about basic statistical concepts

  • Intro to Statistics online at Penn State.

Help @MathCenter

Mathematics graduate students who are TAs hold office hours in our department's Virtual Math Center; check out the Virtual Math Tutoring Center here.
Any TA can help with any course they have some knowledge about, when they are not busy with students in their assigned courses. Make sure you use this great resource!

Help with typing math: TeX, etc.

You are encouraged to type your assignments. You can access LaTeX in the computer labs; more information and help can be found on this departmental page. Note: for Macs, I recommend TeXShop. You can also simply use Overleaf.

You might also consider using the what-you-see-is-what-you-get text editor TeXmacs; it makes it unnecessary for you to learn the LaTeX typesetting language while producing output of comparable quality. The program is freely downloadable, available for various platforms, able to import and export LaTeX files, and offers a plugin for some programming languages.
