Beta distribution reparameterized by mode and concentration
Usage
rbeta2(n, omega, kappa)
dbeta2(x, omega, kappa)
Arguments
- n
Number of samples.
- omega
The mode of the beta distribution, constrained to (0, 1).
- kappa
The concentration parameter of the beta distribution. Are only
defined for values greater than 2.
- x
Vector of quantiles.
Examples
rbeta2(n=5, omega=0.3, kappa=5)
