New! Solutions to homework 5 and 6 posted (linked in the navigation section to the left). Username and password were given out in class.

New! The last slide covered in the last class (Monday, Mar 11) was Deck 5, Slide 12.

New! Solutions to the first midterm posted. (linked in the navigation section to the left). Username and password are the same as for homework solutions and were given out in class.

Midterms moved to Fraser Hall 102 (link to map in exam dates section). Final exam will probably be moved too, but hasn't been moved yet.

The computer rweb.stat.umn.edu is now working, so our computer examples (in the navigation to the left) are now working. In order to make them work you have to (one time) accept an invalid certificate. Google chrome says

Your connection is not private
Attackers might be trying to steal your information from rweb.stat.umn.edu (for example, passwords, messages, or credit cards). Learn more
and suggests you want to go Back to safety. Instead you want to click on the advanced button and accept. Just don't type any personal info of any kind into Rweb. It only understands R anyway.

Material covered on the first midterm is all of slide deck 1 and slides 1–111 of slide deck 2 and homeworks 1–4.

The errata page (in the navigation to the left) is now nonempty. This announces an issue noticed by a student in the preceding class. The slides have been corrected to match the erratum. (It's Latin. Singular erratum, plural errata.)

We are now caught up. Starting Monday Feb 11 all due dates and office hours and tests are as on the general info page and the homework assignments page and the exam dates section of this page.

Not required, but for those who want to know more about coin flips or dice rolls, here is a YouTube video about coin flips by a famous statistician, and here is a two-part YouTube video about dice rolls (Part I and Part II).

Your instructor has a commitment right after class on Fridays (the Biology Interest Group of the Minnesota Center for Philosophy of Science) and so will not be able to hang around after class on Fridays. On Mondays and Wednesdays, I can answer questions at length, even if we have to move the conversation out in the hall.

This web site has no index, so in order to find stuff one needs to use a search engine. Here is how to do that. For example, if you want to find information on the beta distribution, then the search

"beta distribution" site:www.stat.umn.edu/geyer/5101
does that. This works either with Google or with DuckDuckGo. The quotation marks mean find the exact phrase. If they are left off, then the search engine will return results that have the word beta and the word distribution, not necessarily in the same page much less in the same sentence. The magic is the site: part, which tells the search engine only to look in that site. The site can be made more restrictive, for example,
"beta distribution" site:www.stat.umn.edu/geyer/5101/slides
says to look only in the slides (this seems to work only in Google, but not in DuckDuckGo even though it is supposed to work in DuckDuckGo).

This course has no dead tree format syllabus. Instead we have this web site.

For general information see the General Info link in the navigation section to the left.

In particular, note that this class has no textbook. All of the course material is covered in the slides found under the Course Slides link in the navigation section to the left.

For homework assignments see the Homework Assignments link in the navigation section to the left.

This course also has a Canvas site, which is also linked in the navigation section to the left, but we will use that only for the gradebook. Everything else is here.
