Regression Live Lab

Observations are streaming into a regression right now, and the coefficient re-fits in front of you. Your job: notice when the number you would report stops meaning what it used to mean, work out which covariate got tangled up with your predictor, and fix the model — reading the output, not writing the code. Plan on about 30 minutes.

It opens with your Cornell login. The lab lives on the course's own server, so signing in is how it knows who you are — there is no code and no password to type in. Each lab opens on the day we run it in class, so if you are looking ahead and it turns you away, that is expected — come back on the day. If it still turns you away during the session and you are on the roster, tell the instructor rather than hunting for a workaround.
