posterior: Compute posterior distribution

In kkmann/otsd: Adaptive Optimal Two-Stage Designs in R

Compute posterior distribution

Description

Return posterior distribution given observing stage-one outcome.

Usage

posterior(dist, prior, x1, n1, ...)

## S4 method for signature 'DataDistribution,PointMassPrior,numeric'
posterior(dist, prior, x1, n1, ...)

## S4 method for signature 'DataDistribution,ContinuousPrior,numeric'
posterior(dist, prior, x1, n1, ...)

Arguments

dist	a univariate distribution object
prior	a Prior object
x1	stage-one test statistic
n1	stage-one sample size
...	further optional arguments

Value

Object of class Prior

Examples

posterior(Normal(), PointMassPrior(0, 1), 2, 20)

tmp <- ContinuousPrior(function(x) dunif(x, .2, .4), c(.2, .4))
posterior(Normal(), tmp, 2, 20)
