This web page is for error corrections and other changes to the slides and homeworks.

(posted May 17). A bunch of corrections were made to the final exam and its
solutions after they were first posted and, of course, after the exam was
taken. Only two of these were actual errors. In question 7 on the test
the distribution was intended to be continuous with support (0, ∞)
rather than what the test form said (discrete with support 0, 1, 2, …).
No one seemed to have been bothered by this, so no adjustment was made to the
grading. The solution to question 8 originally posted was missing
a ½. The correct answer is
Gamma(n + α, λ + ½ ∑_{i = 1}^{n} x_{i}^{2})In questions 3, 6, and 8 the notation X_{1}, …, X_{n} was added in addition to the IID that was already there. Since this was asked about during the exam, and since
IID implies X_{1}, …, X_{n}
was was written on the blackboard during the exam, no adjustment was made to the grading. Minor changes in wording that do not affect meaning were made in some other places in both the exam form and the solutions.  (posted May 13). F changed to F_{θ} in the table about the parametric bootstrap on slide 11, deck 8. (No an actual error.)
 (posted May 1). Solution to hw 10 reposted. Not sure what the issue was but the one previously posted was behind the source code. So it may have changed some (but I don't know where).
 (posted May 1). For a while, the solution to hw 11 was posted with messed up plots (one duplicated, one in the wrong place, one missing). Fixed by 7:40 am on May 1.
 (posted May 1). Very minor changes to the solutions to homeworks 3, 4, 7, 8, and 11 to make the problem statements exactly match in the homework assignment and the solutions (no changes in the solutions themselves).

(posted Apr 29). A bunch of changes to the proof about likelihood ratio tests.
On slide 33,
∇ l_{n}(θ_{0}) Mhas been changed toM^{T} ∇ l_{n}(θ_{0})so ∇ l_{n}(θ_{0}) is interpreted as a column vector (apparently was supposed to be a row vector before). On slide 36, the four terms in the limit have signs +, −, −, and + (where before they were +, +, −, and −). The reason is that n^{−1} ∇^{2} l_{n}(θ_{0}) converges to − I(θ_{0}) (not + that). On slide 38, the middle line of the threeline displayed equation isU^{T} (I − A M [M^{T} A^{2} M]^{−1} M^{T} A) Unot as it was before with an extra A in there.

(posted Apr 13). Many changes made to deck 5 of the slides.
Most are small changes in wording that do not affect the sense
(slides 40, 44, 50, 60, 63, 77). One (slide 14) strengthens what is
stated. Before it read
If the p columns of M are linearly independent … and p ≤ n, then V is a pdimensional vector space and the map …
If the p columns of M are linearly independent …, then p ≤ n and V is a pdimensional vector space and the map …
 (posted Apr 12). Many changes made to the handout on Markov chain Monte Carlo (no actual changes to calculations, just better explanation). Too many to describe here. Just get another if you printed it out before April 12, 2015.
 (posted Apr 03). Extra wording added on slide 74, deck 4 (no actual errors).
 (posted Mar 25). Some commas added for clarity on slides 13 and 16 of deck 4 (no actual errors).

(posted Feb 20). On slides 197 of deck 2 changed
asymptotically pivotal quantity
toexact pivotal quantity
(the latter being correct in this case).  (posted Feb 17). Some changes in wording for clarity on slides 161 and 162 of deck 2 (no actual errors).
 (posted Feb 13). Added equals sign to the displayed equation on slide 116 of deck 2.
 (posted Feb 12). On slide 138 of deck 2 we changed Y to W because we are in the middle of a discussion that already involves Y_{1}, Y_{2}, … Y_{n} and _{n}. The random variable on this slide has nothing to do with them. Hence the change.
 (posted Feb 4). Slide 122 of Deck 1 had x_{p} where it should have had m. Now fixed.
