Generate a beta distribution out of probabilities, or positive and negative counts

Generate a beta distribution out of probabilities, or positive and negative counts

Usage

beta_dist(..., p = NULL, q = NULL, n = NULL, shape1 = NULL, shape2 = NULL)

Arguments

...

not used

p

the first shape / the probability or count of success

q

(optional) the second shape / the probability or count of failure

n

(optional) the number of trials.

shape1

the first shape parameter (use this to force interpretation as shape)

shape2

the second shape parameter (use this to force interpretation as shape)

Value

either a single beta_dist object or a list of beta_dists

Examples

beta_dist(shape1 = c(1,2,3),shape2 = c(3,2,1))
#> 20.6% [0.8%—70.8%] (N=4.0)
#> 50.0% [9.4%—90.6%] (N=4.0)
#> 79.4% [29.2%—99.2%] (N=4.0) 
beta_dist(p = 0.7, n = 2)
#> 77.3% [10.9%—99.9%] (N=2.0)
