Left-Right Scores based on Franzmann & Kaiser Method

Computes left-right scores based on the Franzmann & Kaiser Method (see reference below). The issue structures are not calculated from scratch but taken as given from Franzmann 2009. Note that they are not available for the entire Manifesto Project Dataset, but only for a subset of countries and elections.

Usage
franzmann_kaiser(data, basevalues = TRUE, smoothing = TRUE,
  vars = grep("per\\d{3}$", names(data), value = TRUE),
  issue_structure = read_fk_issue_structure(mean_presplit = mean_presplit),
  party_system_split = split_belgium, mean_presplit = TRUE, ...)

read_fk_issue_structure(path = system.file("extdata", "fk_issue_structure.sav", package = "manifestoR"), mean_presplit = TRUE)

fk_smoothing(data, score_name, use_period_length = TRUE, ...)

Arguments
data

A data.frame with cases to be scaled, variables named "per..."

basevalues

flag for transforming data to be relative to the minimum

smoothing

flag for using smoothing

vars

Variables/Categories to use for computation of score. Defaults to all available handbook version 4 categories.

issue_structure

issue structure to use for Franzmann & Kaiser method, default to original replication values

party_system_split

function to recode the country variable to re-partition party systems. Defaults to splitting Belgium into two halfs as done in Franzmann 2009

mean_presplit

if TRUE, for Belgium as a whole (before the split into two party systems) the mean of the issue weights is used (which is equal to taking the mean of the output values, since all subsequent transformations are linear). This step is required to replicate the Franzmann 2009 dataset.

...

passed on to fk_smoothing and party_system_split

path

path from were to read issue structures (as SPSS data file). Defaults to the file bundled in the manifestoR package from the replication material of Franzmann 2009.

score_name

name of variable with LR Score values to be smoothed

use_period_length

whether to use electoral period length in weighting
