dbeta(x, a, b) pbeta(q, a, b) qbeta(p, a, b) rbeta(n, a, b)
x,q
| vector of quantiles. |
p
| vector of probabilities. |
n
| number of observations to generate. |
a, b
| positive parameters of the beta distribution. |
a and b. dbeta gives the density,
pbeta the distribution function, qbeta the
quantile function and rbeta generates random deviates.
The Beta distribution has density
Gamma(a+b)/(Gamma(a)Gamma(b))x^(a-1)(1-x)^(b-1)
beta for the beta function, and dgamma for the
Gamma distribution.
