rtbeta(n, alpha, beta, a=0, b=1)
dtbeta(x, alpha, beta, a=0, b=1)
ptbeta(q, alpha, beta, a=0, b=1)
qtbeta(p, alpha, beta, a=0, b=1)

Arguments

x,q

vector of quantiles.

p

vector of probabilities.

n

number of observations. If length(n) > 1, the length is taken to be the number required.

alpha

vector of alpha parameters.

beta

vector of beta parameters.

a

vector of lower truncation limits

b

vector of upper truncation limits

Value

dtbeta gives the density, ptbeta gives the distribution function, qtbeta gives the quantile function, and rtbeta generates random deviates.
