tpexp: The two-parameter exponential distribution(tpexp)

In twopexp: The Two Parameter Exponential Distribution

The two-parameter exponential distribution(tpexp)

Description

Density, distribution function, quantile function, and random generation function for the two-parameter exponential distribution with theta and beta

Usage

dtpexp(x, theta = 0, beta = 1, log = FALSE)

ptpexp(q, theta = 0, beta = 1, lower.tail = TRUE, log.p = FALSE)

qtpexp(p, theta = 0, beta = 1, lower.tail = TRUE, log.p = FALSE)

rtpexp(n, theta = 0, beta = 1)

Arguments

x, q	vector of quantile.
theta	location parameter, where \theta > 0.
beta	scale parameter, where \beta > 0 and rate=1/\beta.
log, log.p	logical; (default = FALSE), if TRUE, then probabilities are given as log(p).
lower.tail	logical; if TRUE (default), probabilities are P[X \le x], otherwise, P[X > x].
p	vector of probabilities
n	number of observations. If length(n) > 1, the length is taken to be the number required.

Value

dtpexp gives the density, ptpexp gives the distribution function, qtpexp gives the quantile function, and rtpexp generates random samples.
