tgamma: Truncated Gamma Functions

In TruncatedDistributions: Use Truncated Distribution functions

Description

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

Usage

rtgamma(n, shape, scale=1, a=0, b=Inf)
dtgamma(x, shape, scale=1, a=0, b=Inf)
ptgamma(q, shape, scale=1, a=0, b=Inf)
qtgamma(p, shape, scale=1, a=0, b=Inf)

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.
shape	vector of shape parameters.
scale	vector of scale parameters.
a	vector of lower truncation limits
b	vector of upper truncation limits

Value

dtgamma gives the density, ptgamma gives the distribution function, qtgamma gives the quantile function, and rtgamma generates random deviates.
