Utilities for the logitnormal distribution in R


The logitnormal distribution is useful as a prior density for variables that are bounded between 0 and 1, such as proportions. Fig. 1 displays its density for various combinations of parameters mu and sigma.

The package provides the main distribution functions:

Transformation functions

Moments and mode

Estimating parameters
