Exactly right, Mr Lakin.

Dear all,
As per the replication results: do we put "all" our replication results on the
sheets we submit on 22nd - or just the significant tables and figures? Please,
advise and cannot thank you enough.

Good mornig everyone,
I have 2 questiions and 1 news.
How to control the number of digits in the presentation of matrix?
As for ps6 #1(b),
when I reparametarize sigma^2 by exp(r)
and get an estimated r and its se,
how can I un-reparametarize r's se into sigma^2's se?
FYI, if you plan to publish your publishable paper,
why don't you make it public at the next year's APSA?

The propsal deadline comes on Nov. 15.

The first election call is for Kerry. We're told the Fox News people look
miserable. Yee ha!!

Hi, everyone.
As I mentioned in section, problem set 6 will be due in lecture
on Monday, Nov. 4th. Problem set 7 will be due in section on
Thursday, Nov. 18th. These problem sets aren't longer than the
other problem sets -- this is intended to give you more time to
work on your papers.
About last week's section and next week's section:
Gary covered two really important concepts in lecture last week:
1) maximum likelihood and 2) interpreting regression output via
simulation. I covered (1) in section this week and will cover
(2) this coming week in section (in other words, I'll present
the Zelig deck from APSA).
As I mentioned to those who showed up, these two sections are
the most important in the course because we're going over how to
write a new model, and a generalized framework for interpreting
output from all statistical models, and irrespective of the
methodology of the original paper, we expect a few things in
your final paper:
1) You should choose a model compatible with the hypothesized
event generating mechanism (and if the model hasn't been
programmed, you should program it yourseif via maximum
likelihood, and if you don't know what I'm talking about, you
need to read the handout for 10/28...)
and
2) You should interpret the regression results in your final
paper by simulating quantities of interest (which is why next
week is important).
So if you couldn't make it to section last Thursday, read the
handout and let me know if you have questions. And you should
come to section this Thursday, because I don't think Gary is
going to go back and cover simulation again.
Yours,
Olivia Lau
