calculate_prob: Calculate coalition probability from majority table

In adibender/coalitions: Bayesian "Now-Cast" Estimation of Event Probabilities in Multi-Party Democracies

Calculate coalition probability from majority table

Description

Given a table with simulations in the rows and coalitions in the columns, this function returns the coalition probabilities for a specified coalition, by default excluding superior coalitions first

Usage

calculate_prob(majority_df, coalition, exclude_superior = TRUE, ...)

Arguments

majority_df	A data frame containing logical values indicating if the coalitions (columns) have a majority (rows).
coalition	The coalition of interest for which superior coalitions will be obtained by get_superior.
exclude_superior	Logical. If TRUE, superior coalitions will be excluded, otherwise total coalition probabilities will be returned. Usually it makes sense to exclude superior coalitions.
...	Further arguments passed to get_superior

Examples

test_df <- data.frame(
 cdu            = c(rep(FALSE, 9), TRUE),
 cdu_fdp        = c(rep(FALSE, 8), TRUE, TRUE),
 cdu_fdp_greens = c(TRUE, TRUE, rep(FALSE, 6), TRUE, TRUE))
calculate_prob(test_df, "cdu_fdp_greens") # exclude_superior defaults to TRUE
calculate_prob(test_df, "cdu_fdp_greens", exclude_superior=FALSE)
