Getting started with Github Classroom

Go to Github classroom to accept the invitation to create a repository for this assignment.

This will create a private repo in the STA721-F24 organization on Github with your github user name. Note: You may receive an email invitation to join STA702-F24 on your behalf.

Hit refresh, to see the link for the repo, and then click on it to go to the STA721-F24 organization in Github.

Follow the instructions in the README in your repo and in the hw#.Rnw file to complete the assignment and push to GitHub. If you encounter issues with Gradescope submission, it is critical that you have pushed your final assignment to GitHub by the due date to validate timestamps.

R & RNW

You are required to use the .Rnw format to type up this report report if there are any R problems. To get started see Knitr with LaTeX article by Karl Broman. Feel free to include images of technical derivations if you are short of time to typeset in LaTeX. The macros.tex file should help with shortcuts. You may need to change some of your Project or Global options to get your document to compile with KnitR. If so please post under Ed in the General category or ask in Lab.
