See stats::Beta

Usage

dist_beta(shape1 = NULL, shape2 = NULL, ncp = NULL)

Arguments

shape1

First scalar shape parameter, or NULL as a placeholder.

shape2

Second scalar shape parameter, or NULL as a placeholder.

ncp

Scalar non-centrality parameter, or NULL as a placeholder.

Value

A BetaDistribution object.

Details

All parameters can be overridden with with_params = list(shape = ..., scale = ...).
