I asked the library to put it on hold but they don't have a copy. So you'll need to get a copy, or get access to a copy from another student, before next week. I won't continue to type up the whole problem set each week. Fri, 14 Sep 2007 11:00:00 -0500 I just sent a message to those of you in the google-group, as I've discovered that signing up for it may be more complex than simply clicking on the link. If you didn't get the message you will have to create a google groups account to actually join the group. Fri, 14 Sep 2007 11:00:00 -0500 Yanping's office hours have changed: they will be Tuesday 9:40-10:40am and Thursday 2:30-3:30pm. Thu, 13 Sep 2007 09:30:00 -0500 I just downloaded the current list of registered students and sent an email to each of you. It has the sentence "If you didn't get this email, there's a glitch somewhere." If you in fact didn't get this message, please let me know so we can fix the glitch. Also, if you register after today, please let me know so I can add you to the list. Mon, 10 Sep 2007 20:00:00 -0500 Homework 2, due September 19, has been posted.

Wed, 5 Sep 2007 16:00:00 -0500 In class today I meant to talk more about the prerequisites, and some of you may have been misled by my survey. In short, there are no statistics prereqs for this class, nor is multivariate calculus required, though we will need some multivariate calculus, and we'll learn it when the time comes. I asked about your preexisting knowledge because I know this class attracts a wide variety of students with varying backgrounds, and knowing the specific makeup of this class will help me prepare better. To repeat, you should be able to succeed in this class even if you have had no statistics classes before and don't know multivariate calculus. Wed, 5 Sep 2007 16:00:00 -0500 A google-group has been set up for you to be able to send messages to each other (and to me) about homework, review questions, and things relating to the class. I will not distribute any information using this group; so it is not required at all that you join it. it's purpose is to provide an online place where you can discuss the topics of this course. The web site is http://groups.google.com/group/um-theory-of-statistics. I think you can request to join from this page; otherwise I will be sending out invitations shortly. Wed, 5 Sep 2007 16:00:00 -0500 There will be no lab section on Tuesday, September 4. However, the TA will be there to answer questions. Wed, 29 Aug 2007 15:00:00 -0500
