* Example for questionnaire scenario Trees&Fountains: ExampleQuestionnaireTreesAndFountains.pdf
* Example cover letter: ExampleCoverLetter.pdf
* Example reminder postcard: ExampleReminderPostcardWithoutAddress.pdf

2) Data and code: These are the original data prepared for the analysis and code in the statistical laguage R (www.r-project.org)
The file names end with the version number to keep track of potnential future changes.
Files ending with .R can be read by standard text editors
Files ending with .RData are binary R files.
It is best to place all these fils in one directory

* Data in csv format.RData (delimiter =",", comma = "."): ReplicationData_v002.csv
* Data in the binary R format.RData: ReplicationData_v002.RData
* Description of the variables as .txt file: description_variables_003.txt
* Code of the main file for the analysis. Start with this file. From this file the other .R files are sourced: RcodeMainFile.R
* Code for the interval Regression: inveralLinearRegression_v002.R
* Code for the interval Regression when dropping "protest votes" (this is only run when activated in the RcodeMainFile.R): inveralLinearRegression_whenDroppingProtestVotes_v002.R
* Code for the bootstrapping: bootstrapping_v003.R
* Code for modified summary function for the results of the bootstrapping: boot.summary.modified.R
