Compute posterior distribution

Return posterior distribution given observing stage-one outcome.

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

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

# S4 method for DataDistribution,PointMassPrior,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

tmp <- ContinuousPrior(function(x) dunif(x, .2, .4), c(.2, .4))
posterior(Normal(), tmp, 2, 20)
#> ContinuousPrior<[0.2,0.4]> 

posterior(Normal(), PointMassPrior(0, 1), 2, 20)
#> PointMass<0.00>
