In jgodet/utilitR: Lots of useful functions

Bayesian comparison of two means

Description

Bayesian comparison of two means

Usage

B2mean(
  var1,
  var2,
  n.iter = 11000,
  n.burnin = 1000,
  n.thin = 1,
  prior.norm = c(0, 0.001, 0, 0.001),
  prior.gamma = c(0.5, 0.5, 0.5, 0.5)
)

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.norm	normal parameters for priors of means 1 and 2 - two parameters each (mean, precision)
prior.gamma	gamma parameters for priors of tau 1 and tau 2 - two parameters each (shape, rate)

Details

precision is the inverse of variance

Value

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

Examples

x <- rnorm(200, 2.1, .4)
y <- rnorm(200, 2, .4)
B2mean(var1=x, var2=y)
