Method new()

Create a new object of class distribution.continuous.exponential.class

Usage

distribution.continuous.exponential.class$new(rate = 1)

Arguments

rate

The rate of the exponential distribution

---

Method d()

Density function for an exponential random variable with rate params$rate.

Usage

distribution.continuous.exponential.class$d(x, log = FALSE)

Arguments

x

vector of quantiles.

log

logical; if TRUE, probabilities p are given as log(p).

---

Method p()

Cumulative density function for an exponential random variable with rate params$rate.

Usage

distribution.continuous.exponential.class$p(
  q,
  lower.tail = TRUE,
  log.p = FALSE
)

Arguments

q

vector of quantiles.

lower.tail

logical; if TRUE (default), probabilities are \(P[ X \leq x ]\), otherwise, \(P[X>x]\).

log.p

logical; if TRUE, probabilities p are given as log(p).

---

Method q()

Quantile function for an exponential random variable with rate params$rate.

Usage

distribution.continuous.exponential.class$q(
  p,
  lower.tail = TRUE,
  log.p = FALSE
)

Arguments

p

vector of probabilities.

lower.tail

logical; if TRUE (default), probabilities are \(P[ X \leq x ]\), otherwise, \(P[X>x]\).

log.p

logical; if TRUE, probabilities p are given as log(p).

---

Method r()

Generates random deviates for an exponential random variable with rate params$rate.

Usage

distribution.continuous.exponential.class$r(n)

Arguments

n

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

---

Method clone()

The objects of this class are cloneable with this method.

Usage

distribution.continuous.exponential.class$clone(deep = FALSE)

Arguments

deep

Whether to make a deep clone.
