plot_beta_ci function

Plot a Beta Model with Credible Interval

Plots the probability density function (pdf) for a Beta(alpha, beta) model of variable $\pi$ with markings indicating a credible interval for $\pi$.

plot_beta_ci(alpha, beta, ci_level = 0.95)

Arguments

• alpha, beta: positive shape parameters of the Beta model
• ci_level: credible interval level

Returns

A density plot for the Beta model

Examples

plot_beta_ci(alpha = 7, beta = 12, ci_level = 0.80)
