Overview
Today we finish our discussion of statistical inference, focusing on hypothesis testing about our regression. We will hopefully have time at the end to work on a few practice problems.
Readings
- Ch.4 in Bailey, Real Econometrics
- Ch. 10 (optionally 8-9) in Modern Dive
- Visualizing Probability and Inference
- Last Week Tonight with John Oliver: Scientific Studies
- “There is Still Only One Test”
The readings are the same as last class, plus one highly recommended additional video: be sure to watch the excellent and hilarious discussion of the limits and misuses of scientific studies and statistical significance \((p\)-values) in the Last Week Tonight clip. I also added the blog post that I reference in class about all hypothesis testing is really one common procedure.
Slides
Below, you can find the slides in two formats. Clicking the image will bring you to the html version of the slides in a new tab. Note while in going through the slides, you can type h to see a special list of viewing options, and type o for an outline view of all the slides.
The lower button will allow you to download a PDF version of the slides. I suggest printing the slides beforehand and using them to take additional notes in class (not everything is in the slides)!
R Practice
Today you will be working on R practice problems on regression. Answers will be posted later on that page.
