Shifted Exponential Distribution

Description

Calculations for shifted exponential distribution, sometimes called the exponential(low) distribution. This is equivalent to a regular exponential distribution, but shifted on the X axis left or right so that it has a non-zero origin. It can be specified in two ways, using a minimum and rate parameter or using a minimum and mean parameter.

Usage

dexp.low(x, rate = 1, low = 0, log = FALSE)

pexp.low(q, rate = 1, low = 0, mean = NA, lower.tail = TRUE, log.p = FALSE)

qexp.low(p, rate = 1, low = 0, mean = NA, lower.tail = TRUE, log.p = FALSE)

rexp.low(n, rate = 1, low = 0, mean = NA)

Arguments

x	Scalar - numeric - quantile.
rate	Scalar - numeric - distribution rate.
low	Scalar - numeric - Minimum distribution value.
log	Scalar - logical - if true, probabilities reported as log(p).
q	Scalar - numeric - quantile.
mean	Scalar - numeric - mean of distribution. If specified, rate is 1/(mean-low)
lower.tail	Scalar - logical - if true, probabilities are lower tail probabilities.
log.p	Scalar - logical - if true, probabilities reported as log(p).
p	Scalar - numeric - probability.
n	Scalar - integer - number of observations.

Value

dexp.low returns density function, pexp.low returns distribution function, qexp.low returns quantiles, and rexp.low returns random value(s).
