• Minor clarifications on the homework. For problem 3.2, assume that $\theta \in \theta^d$ where $d=1$. Hence, the Gaussian random variables are univariate. For 3.1 (c), \sqrt{ \det(\Gamma) } should be in the numerator, not the denominator. The \sqrt{2 pi} term should read (2 pi)^{d/2}, there is a missing $d$ in the problem set.
• THIS WEEK ONLY (Tuesday Oct 21). Prof. Wainwright will not have his usual OH from 11--12. Instead, Sahand will have an extra office hour at the same time; location: 611 Soda (same place as Sahand's usual office hours)

If there is a group of students, everybody goes over to Evans Hall 330. If you want to join later, try Evans Hall 330, or Prof. Wainwright's office, Evan Hall 421.
