Truncated exponential distribution functions

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

rtexp(n, rate, a = 0, b = Inf)

dtexp(x, rate, a = 0, b = Inf)

ptexp(q, rate, a = 0, b = Inf)

qtexp(p, rate, a = 0, b = Inf)

Arguments

n

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

vector of rate parameters.
a

vector of lower truncation limits
b

vector of upper truncation limits
x, q

vector of quantiles.
p

vector of probabilities.

Value

dtexp gives the density, ptexp gives the distribution function, qtexp gives the quantile function, and rtexp generates random deviates.
