## Draw random numbers from posterior distribution

### Description

Draw random numbers from posterior distribution

### Usage

draw_from_posterior(
survey,
nsim = 10000,
seed = as.numeric(now()),
prior = NULL,
correction = NULL
)


### Arguments

 survey survey object as returned by as_survey or getSurveys nsim number of simulations seed sets seed prior optional prior information. Defaults to 1/2 (Jeffrey's prior). correction A positive number. If not NULL, each sample from the Dirichlet distribution will be additionally "corrected" by a random number from U(-1*correction, 1*correction). This can be used to introduce extra variation which might be useful due to rounding errors from reported survey results (or add an additional source of variation in general).

### Value

data.frame containing random draws from Dirichlet distribution which can be interpreted as election results.
