POLI 279 MEASUREMENT THEORY
Eighth Assignment
Due 6 June 2007

1. In this problem we are going to use Simon Jackman's Bayesian MCMC Quadratic-Normal scaling program IDEAL to estimate two-dimensional ideal points for the 104th Senate.

idealKeith2_2007.r -- Program to run IDEAL on the 104th Senate.

idealKeith2_2007.r looks like this:
#
#
#  idealKeith2_2007.r -- Implements Simon's IDEAL in R
#
rm(list=ls(all=TRUE))
#
library(pscl)
#
yea=c(1,2,3),
nay=c(4,5,6),
missing=c(7,8,9),
notInLegis=0,
desc="104th U.S. Senate",
debug=FALSE)
class(s104)
csts <- constrain.legis(s104,x=list("KERRY (D MA)"=c(-1,0),
"HELMS (R NC)"=c(1,0),
"NUNN (D GA)"=c(0,1)),d=2)
kpideal <- ideal(s104, d=2, priors=csts, startvals=csts, store.item=TRUE)
sumkpideal <- summary(kpideal,include.beta=TRUE)
#
write.table(sumkpideal\$x,"c:/ucsd_homework_8/tab_simon_104_2x.txt")
write.table(sumkpideal\$bResults,"c:/ucsd_homework_8/tab_simon_104_2z.txt")
#
#
This is essentially the same syntax as the one-dimensional version used in Question 4 of Homework 7.

After you run the two-dimensional IDEAL the legislator ideal point file will look something like this:

"Mean" "Std.Dev." "X2.5." "X97.5." "Mean.1" "Std.Dev..1" "X2.5..1" "X97.5..1"

The first and fifth columns of numbers are the Posterior Means for the first and second dimensions.

1. Write an Epsilon macro that nicely formats this file (be sure to remove the "'s!). Turn in a neatly formatted listing of the file along with the macro (note that you might want to use the SPACE bar in the macro).

2. Use R to plot the legislators in two dimensions from the file you just created in (a). Use "D" for Non-Southern Democrats, "S" for Southern Democrats, "R" for Republicans, and "P" for President Clinton.

3. Replicate the above plot and add crosshairs for each Senator corresponding to the 95% quantiles. Neatly label the tokens for President Clinton, Senator John McCain, and Senator Edward Kennedy.

4. Compare the two-dimensional coordinates from IDEAL with those you estimated using Optimal Classification in Problem 1.c of Homework 5. In particular, rotate the IDEAL coordinates so that the best match the Optimal Classification coordinates using the method shown in detail in Problem 2.g of Homework 7. Report the Pearson r-squares before and after rotating.

5. Put the IDEAL coordinates and Optimal Classification coordinates in STATA and run the following regressions:

OC-1st = b0 + b1(IDEAL-1st) + b2(IDEAL-2nd)

OC-2nd = b0 + b1(IDEAL-1st) + b2(IDEAL-2nd)

Report the standard STATA output for both of these regressions.

2. In this problem we are going to use metric unfolding to analyze the thermometer scores from the 2004 election study in the same way that we did for question 3 of Homework 5. Download the the program, control card file, and data file and place them in the same directory.

1. Use R to plot the 14 candidates/Political Figures in two dimensions. This plot should be very similar to the one you did for question 3 of Homework 5.

2. Use Epsilon to insert the voted and voted for variables into FORT.22 (strip off the candidate coordinates first). Turn in the Epsilon macro you used to do the insertion and the first 20 lines of the file.

3. Use R to make two-dimensional plots of the Voters, Non-Voters, Bush Voters only, and Kerry Voters only. Label each plot appropriately and use solid dots to plot the respondents. Turn in all these plots.

4. Use R to make smoothed histograms -- using the first dimension from the thermometer scaling -- of the Voters and Non-Voters only, and the Kerry Voters, Bush Voters, and Non-Voters. Your Bush-Kerry-NonVoters plot should look like the one for Question 4.d of Homework 5.

3. The aim of this problem is to analyze the 2004 Liberal-Conservative 7-Point Scale with the Aldrich-McKelvey scaling program (we used this program in Question 2 of Homework 5). Download the "control card" file:

2004 Liberal-Conservative Control Card File

and place it, MCKALNEW.EXE, and elec2004.dat hem in the same folder on a WINTEL machine. Read the Aldrich-McKelvey scaling program page to see how to run the program.

1. Use R to make smoothed histograms of Democrats (0,1,2), Independents (4), and Republicans (4,5,6) over the scaled positions. Be sure the graph is neatly formatted and labeled like the one shown in Question 2.f of Homework 6.

2. Use R to make smoothed histograms of just the Strong Democrats (0) and the Strong Republicans (6).
