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