tnInvlogit - Invlogit-transformed distribution

Invlogit-transforms a given distribution.

Usage

tnInvlogit(Distribution__Real baseDistribution)

Arguments

baseDistribution : Distribution__Real (pass by const reference)
The distribution to be transformed.

Domain Type

Probability

Details

If X ~ dist then tnInvlogit(dist) is the distribution of exp(X)/(1+exp(X)). The inverse logit function is also called the logistic function. The distribution `dist` can be either univariate (dnNormal) or multivariate (MultivariateNormal).

Example

p ~ tnInvlogit(dnNormal(0,1))      # The inverse-logit of a Normal random variable.
p ~ dnNormal(0,1) |> tnInvlogit()  # Expressed using pipes.

x ~ dnNormal(0,1)
p := invlogit(x)                   # Expressed as a deterministic function of the log-odds.

ps ~ dnIID(4,dnNormal(0,1)) |> tnInvlogit()

mu = [1.0, 2.0, 3.0, 4.0]
Sigma ~ dnWishart(df=4, kappa=2, dim=4)
x ~ dnMultivariateNormal(mu,Sigma) |> tnInvlogit()
