EI Diagnostic - Estimating Crossover Voting in California Top 2 Primary

by Woo Chang KANG

Hello, I am using EI to estimate crossover voting in the Top 2 Primary in California in 2012. The unit of analysis is at the precinct level and I match the turnout record of partisan voters with election return data. For simulation, I use the following formula. formula <- cbind(dem.return, rep.return, oth.return) ~ cbind(dem.show, rep.show, oth.show) dem.return : Vote Share of a Democratic Candidates at the precinct level rep.return : Vote Share of a Republican Candidates oth.return : Vote Share of a Non-Two Party Candidate dem.show : Ratio of Democratic Registered Voters among who casted ballot for the primary rep.show : Ratio of Republic Registered Voters among who casted ballot for the primary oth.show : Ratio of Non-two Party Voters among who casted ballot for the primary My quantity of interests are the ratio of democratic registered voters who voted for the republican candidates (Democratic Crossover to Republican Party) and the ratio of republican registered voters who voted for the democratic candidates (Republican Crossover to Democratic Party). Using precinct level data, I am trying to estimate population weighted average of crossover voting at the State Assembly District. In some districts, the estimate looks reasonable. However, in other districts, my estimates suggest that more than half of each partisan voters crossover to other parties. I wonder what would be the best way to examine how reasonable my EI estimates are. Thank you for your help.

Question about EzI

by Germán Rosati

Hello again. I have a question regarding EzI software. I have a dataset with electoral data desaggregated up to county level. I have run the model with presidential vote in one year as "t" and legislative vote in a previous year as "x". Since the dataset contains data up to county level, I want to export the estimates results in order to make a georeferentiation. When I export those estimates there is not an indicator (ID), so I can´t know to which county correspond each estimate. Is the order in which those estimates are exported the same as in the original database? If not, how can I know which estimate correspond to which county? Sorry for troubling you again. Thank you very much, Bests regards, Germán Rosati PS: I´m sorry for my (not very elegant) english

training on using EI

by Douglas Johnson

Is there anyone on this list, preferably in the LA area, that would be interested in providing some consulting / training on EI in Jan or Feb? I'm looking to get up to speed quickly on the mechanics of using the software (I've read the books & articles and understand the ideas, now just need to learn the technical details of running the program). Thanks! - Doug Douglas Johnson, Fellow Rose Institute of State and Local Government at Claremont McKenna College douglas.johnson(a)cmc.edu 310-200-2058

I'm trying to use ei within R, but I've been unable to extract the ei files from the tar package. I get an "error/warning" message. I've enlisted my computer help desk; the same thing happens when they try to extract the files. Any suggestions? Barry
