beta_params: Compute parameters of a beta distribution

In rpruim/CalvinBayes: Support for Computational Bayesian Analysis Courses

Description

Given two parameters which characterize a beta distribution, compute the remaining parameters in the following set shape1 (a), shape2 (2), mean, mode, sd, and concentration (k).

Usage

beta_params(
  shape1 = NULL,
  shape2 = NULL,
  mean = NULL,
  sd = NULL,
  concentration = NULL,
  mode = NULL,
  a = shape1,
  b = shape2,
  k = concentration,
  plot = FALSE,
  ...
)

Arguments

shape1, a	first shape parameter
shape2, b	second shape paramter
mean	mean of beta distribution
sd	standard deviation of beta distribution
concentration, k	concentration of beta distribution
mode	mode of beta distribution
plot	logical indicating whether a plot of the distribution should be displayed.
...	additional arguments passed to ggformula::gf_dist() to modify the plot produced if plot == TRUE.

Examples

beta_params(10, 5)
beta_params(mean = 0.8, concentration = 10)
beta_params(mean = 0.8, k = 10)
beta_params(mode = 0.8, concentration = 10)
beta_params(mode = 0.8, k = 10)
beta_params(mode = 0.8, k = 10, plot = TRUE, color = "red")
