[gov2001-l] sections and problem sets

by olau＠fas.harvard.edu

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

[gov2001-l] papers

by olau＠fas.harvard.edu

Hi, everyone. I've had several requests for help on loading data and other basic R stuff related to your papers. If you need help, please come to OH -- Tuesdays from 3-5pm, or by appoinment. I can't do this stuff over email. Also, those of you with large datasets have realized that you can't use Windows R for your replication assignment. You'll need to use the servers if you have a lot of data. If your data is so large that you exceed your unix account quota, you can ask FAS directly for an increase to 200MB and can ask your department administrators (Thom Wall or the equivalent) for an increase to 400MB. If you have data that's tab-delimited, space-delimited, comma separated, SPSS or STATA data, you can read your data directly into R following the directions in Zelig Chapter 3, section 2.2. If your data is in another format, you need to convert your data using DBMS copy, which is available in the HMDC and CBRSS computer labs. Yours, Olivia Lau

[gov2001-l] 4 questiuons

by fukumoto＠dg8.so-net.ne.jp

Hi, Does anybody know... 1) How to clean up a R console? 2) In LaTeX, how to show the date other than \today by \maketitle? 3) When I do coauthor work, I highlight what parts I revise on Word. How can we do this by XEmacs? 4) what is the natural conjugate prior distribution of negative binomial (poisson * gamma) or beta? (I do not ask beta is conjugate for what distribution (actually, for bernoulli related distributions.)) Thank you in advance! Kentaro

[gov2001-l] log of a gamma function

by emans＠fas.harvard.edu

In case anyone else was confused by that log of gamma thing, Olivia just confirmed that it is the SAME thing in R to do: log (gamma(a + b)) or lgamma(a+b)

[gov2001-l] Fw: Clarification

by olau＠fas.harvard.edu

A good question, Sara. For question 1 and 2(a), you should show some math. For questions 2(b) and and 3, you should do it in R. (You can check your math with R and your R with math, if you want, but that won't be graded.) ----- Original Message ----- From: "Sara Bleich" <bleich(a)fas.harvard.edu> To: "Olivia Lau" <olau(a)fas.harvard.edu> Sent: Wednesday, October 27, 2004 5:03 PM Subject: Clarification > Olivia, > > For the problem set, I just wanted to clarify whether we should be writing > down the likelihood functions for the various questions in R or by hand. > If > it is in R, does that apply to the analytic solution for the Poisson? > Thanks. > > Sara >

[gov2001-l] slightly revised problem set

by olau＠fas.harvard.edu

Hi, people. Per Kentaro and Paul's comments this weekend, I've posted a revised problem set -- the typos weren't major so I hope this hasn't held anyone up. And as a reminder: I do have OH from 3-5 on Tuesday afternoon. Please come by if you need help with your papers as well. Yours, Olivia.

[gov2001-l] Formal Political Theory Job Talks (fwd)

by king＠harvard.edu

this is entirely voluntary of course, but if you are interested in academia, I would strongly recommend that you all attend these talks. You'll be in the same position as them one day soon, and having a good feel for how these job talks go -- and what works and what doesn't -- will be exceptionally useful for you. there are some principles of what works, but its mostly clinical knowledge and so seeing it in action can help a lot. and quite separately, i'm chair of the cttee, and so if you have any views about the candidates, I'd appreciate if you let me know. Gary ---------- Forwarded message ---------- Date: Mon, 25 Oct 2004 08:48:28 -0400 From: Jaronica Fuller <jfuller(a)latte.harvard.edu> To: Gov_Senior(a)latte.harvard.edu, Gov_Junior(a)latte.harvard.edu Subject: Formal Political Theory Job Talks Dear Government Faculty, Enclosed is the list of junior faculty recruitment candidates for the Formal Political Theory junior faculty search. Also included are the dates for each candidate visit, job talk titles, presentation times and room locations. Please feel free to attend the job talk presentations. If you would like to schedule a 30 minute interview with any of the candidates or if you have any other questions, please feel free to contact me at 496-1512 or jfuller(a)latte.harvard.edu Sincerely, Jaronica C.

[gov2001-l] question

by fukumoto＠dg8.so-net.ne.jp

Hi, In ps#5, 2(b), should we plot the likelihood function with \lambda, not $y$ as indicated, on the x-axis? Also, as for solution set #4, p. 7, should l. 4 read sample.sd[i] <- (N*prob*(1-prob))/i ? Kentaro

[gov2001-l] Q1 question

by aeggers＠gmail.com

My study group and I are confused about the relationship between the student t distribution and what we create in part 1. In particular, what values of nu and s^2 should make our distribution look like a t-distribution of n-degrees of freedom? Andy
