tbeta: Truncated Beta Functions

In TruncatedDistributions: Use Truncated Distribution functions

Description

pdf, cdf, inverse cdf, and random deviates of the truncated beta distribution.

Usage

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.
