Improper priors

largerThan :: Double -> Double -> Log Double

Improper uniform prior; strictly larger than a given value.

positive :: Double -> Log Double

Improper uniform prior; strictly larger than zero.

lowerThan :: Double -> Double -> Log Double

Improper uniform prior; strictly lower than a given value.

negative :: Double -> Log Double

Improper uniform prior; strictly lower than zero.

Continuous priors

exponential

Arguments

:: Double

Rate.

-> Double

-> Log Double

Exponential distributed prior.

gamma

Arguments

:: Double

Shape.

-> Double

Scale.

-> Double

-> Log Double

Gamma distributed prior.

normal

Arguments

:: Double

Mean.

-> Double

Standard deviation.

-> Double

-> Log Double

Normal distributed prior.

uniform

Arguments

:: Double

Lower bound a.

-> Double

Upper bound b.

-> Double

-> Log Double

Uniform prior on [a, b].

Discrete priors

poisson

Arguments

:: Double

Rate.

-> Int

-> Log Double

Poisson distributed prior.

Auxiliary functions

product' :: [Log Double] -> Log Double

Intelligent product that stops when encountering a zero.

Use with care because the elements are checked for positiveness, and this can take some time if the list is long and does not contain any zeroes.
