dnBeta - Beta Distribution

The Beta probability distribution.

Usage

dnBeta(RealPos alpha, RealPos beta)

Arguments

alpha : RealPos (pass by const reference)
The alpha shape parameter.
beta : RealPos (pass by const reference)
The beta shape parameter.

Domain Type

Probability

Details

The Beta distribution is a probability distribution defined on 0 to 1.

Example

p ~ dnBeta(1.0,1.0)
x ~ dnBernoulli(p)
x.clamp(1)
moves[1] = mvSlide(p, delta=0.1, weight=1.0)
monitors[1] = screenmonitor(printgen=1000, separator = "        ", x)
mymodel = model(p)
mymcmc = mcmc(mymodel, monitors, moves)
mymcmc.burnin(generations=20000,tuningInterval=100)
mymcmc.run(generations=200000)
