This dataframe contains the estimated ideal points of the 90th U.S Senate
using oc
. Although it can easily be obtained from calling
the example in oc
, it is included here to facilitate illustration
of the examples for the plot and summary functions.
data(sen90oc)
An object of class OCobject
, with elements as follows:
data frame, containing all data from the old perf25.dat
file about
legislators. For a typical ocObject
run with an ORD file read using
readKH
, it will contain the following:
state
State name of legislator.
icpsrState
ICPSR state code of legislator.
cd
Congressional District number.
icpsrLegis
ICPSR code of legislator.
party
Party of legislator.
partyCode
ICPSR party code of legislator.
rank
Rank ordering of legislator on the first dimension, from lowest to highest.
correctYea
Predicted Yeas and Actual Yeas.
wrongYea
Predicted Yeas and Actual Nays.
wrongNay
Predicted Nays and Actual Yeas.
correctNay
Predicted Nays and Actual Nays.
volume
Measure of the legislator's polytope size.
coord1D
First dimension OC score, with all subsequent dimensions
numbered similarly.
data frame, containing all data from the old perf21.dat
file about
bills. For a typical OCobject
object run with an ORD file read
using readKH
, it will contain the following:
correctYea
Predicted Yeas and Actual Yeas.
wrongYea
Predicted Yeas and Actual Nays.
wrongNay
Predicted Nays and Actual Yeas.
correctNay
Predicted Nays and Actual Nays.
PRE
Proportional Reduction In Error.
normvector1D
First dimension of the unit normal vector, with all subsequent dimensions
numbered similarly.
midpoints
The projection of the normal vector needed to get the midpoint.
integer, number of dimensions estimated.
A vector of roll call eigenvalues.
A vector of length 2 with the classic measures of fit, containing the percent correct classification and the APRE.
