Beta distribution — Beta • distspec

A beta distribution as a <dist_spec>, given either by its shape parameters shape1/shape2 or by its mean/sd. It is not discretised.

Usage

Beta(shape1, shape2, mean, sd, ...)

Arguments

shape1, shape2: Shape parameters of the beta distribution.
mean, sd: Mean and standard deviation of the distribution, as an alternative to shape1/shape2.
...: Limits of the distribution, passed to bound_dist().

Value

A <dist_spec>.
