Beta-binomial distribution
Description
Density and random generation for the Beta-binomial distribution with parameters size
, mu
, and theta
.
Usage
rbetabinom(n = 1, size, prob, theta)
dbetabinom(x, size, prob, theta, log = FALSE)
Arguments
n |
integer; number of random variates to generate. |
size |
|
prob |
mean of the Beta distribution |
theta |
Beta distribution dispersion parameter |
x |
vector of non-negative integer quantiles |
log |
logical; if TRUE, return logarithm(s) of probabilities. |
Details
A variable X
is Beta-binomially distributed if
X\sim{\mathrm{Binomial}(n,P)}
where P\sim{\mathrm{Beta}(\mu,\theta)}
.
Using the standard (a,b)
parameterization, a=\mu\,\theta
and b=(1-\mu)\,\theta
.
Value
rbetabinom |
Returns a vector of length |
dbetabinom |
Returns a vector (of length equal to the number of columns of |
