Bayesian comparison of two proportions

Description

Cod to compare two proportions using bayesian model with beta priors

Usage

B2prop(
  var1,
  var2,
  n.iter = 11000,
  n.burnin = 1000,
  n.thin = 1,
  prior.beta = c(1, 1, 1, 1)
)

Arguments

var1	variable 1
var2	= variable 2
n.iter	number of iteration
n.burnin	number of iteration used in the update of the model
n.thin	n thin
prior.beta	beta priors (vector of 4 parameters, two first for var1)

Value

list with Stats (descriptive stats) and MCMC (inference)

Examples

dtf<-data.frame(grp=c(rep("A",15),rep("B", 15)),
                res=c(rbinom(n = 15, size = 1, prob = .5),
                      rbinom(n = 15, size = 1, prob = .49)) )

res <- B2prop(var1 = dtf$res[dtf$grp=="A"], var2 = dtf$res[dtf$grp=="B"])
res
