generate_discrete_copula_based: Discrete Copula based scores

Description

This function generates discrete scores following marginals distributions linked by a copula #'

Usage

generate_discrete_copula_based(
  n_voters,
  n_candidates,
  min = 0,
  max = 10,
  margins = list("default"),
  cor_mat = 0
)

Value

A matrix of scores with 'n_candidates' rows and 'n_voters' columns.

Arguments

n_voters

integer, the number of voters to generate scores for.

n_candidates

integer, The number of candidates to generate scores for.

min

The minimum value of the distribution, by default 0

max

The maximum value of the distribution, by default 10

margins

A list of n_candidates cumulative distribution vectors of length (max-min-1) : the last value of the cumulative distribution, 1, should be omitted. By default margin distribution are uniform distributions.

cor_mat

A matrix of correlation coefficients between the n_candidates distributions. By default all correlation coefficients are set up alternatively to 0.5 or -0.5.

Examples

# Example for 3 candidates, binomial distributions
 min=0
 max=7
n_candidates<-3
distribution<-dbinom(x=(min:max), size=max, prob=0.7)
distribution_cumul<-cumsum(distribution)
distribution_cumul<-distribution_cumul[-length(distribution_cumul)]
margins <- matrix(rep(distribution_cumul, n_candidates), ncol=n_candidates)
margins <-as.list(as.data.frame(margins))
cor_mat<-matrix(c(1,0.8,0,0.8,1,0, 0,0,1), ncol=n_candidates)
voting_situation <- generate_discrete_copula_based(10, 3, max=max, margins=margins, cor_mat=cor_mat)
