lowerCombined: State Legislative District (Lower Chambers) Public Opinion...

In lbaole17/krige.ext: Geospatial Kriging with Metropolis Sampling (Experimental Version)

Description

These data present measures of ideology in 2010 for the districts for lower chambers of state legislatures, recorded as the variable krige.lower. 49 states' chambers are covered–the Nebraska Unicameral is omitted here to be included in the file upperCombined. 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 House member (or members) from the district (update from Shor and McCarty 2011).
