Finds the alpha and beta parameters for a beta distribution that gives the desired mean and variance

find_beta_prior_with_mean_var(mean, var, make_plot = FALSE)

Arguments

mean

the mean of the beta distribution (between 0 and 1)

var

the variance of the beta distribution (this is likely going to be somewhere less than 0.25)

make_plot

if TRUE, plots the resulting beta distribution to the R device

Value

a list with alpha and beta
