upperCombined | R Documentation |
These data present measures of ideology in 2010 for the districts for upper
chambers of state legislatures, recorded as the variable krige.upper
.
All 50 states' chambers are covered (including the Nebraska Unicameral).
Forecasts are based on a kriging model fitted over the 2008 Cooperative Congressional
Election Survey (CCES), paired with predictive data from the 2010 Census. Each
district's public ideology is paired with a measure of the ideology of the State
Senate member from the district (update from Shor and McCarty 2011).
The upperCombined
dataset has 1989 observations and 10 variables.
