##### The Censored Logistic Distribution

Density, distribution function, quantile function, and random generation for the left and/or right censored logistic distribution.

- Keywords
- distribution

##### Usage

`dclogis(x, location = 0, scale = 1, left = -Inf, right = Inf, log = FALSE)`pclogis(q, location = 0, scale = 1, left = -Inf, right = Inf,
lower.tail = TRUE, log.p = FALSE)

rclogis(n, location = 0, scale = 1, left = -Inf, right = Inf)

qclogis(p, location = 0, scale = 1, left = -Inf, right = Inf,
lower.tail = TRUE, log.p = FALSE)

##### 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.- location
location parameter.

- scale
scale parameter.

- left
left censoring point.

- right
right censoring point.

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

- lower.tail
logical; if TRUE (default), probabilities are P[X <= x] otherwise, P[X > x].

##### Details

If `location`

or `scale`

are not specified they assume the default values
of `0`

and `1`

, respectively. `left`

and `right`

have the defaults `-Inf`

and `Inf`

respectively.

The censored logistic distribution has density \(f(x)\):

\(\Lambda((left - \mu)/\sigma)\) | if \(x \le left\) |

\(1 - \Lambda((right - \mu)/\sigma)\) | if \(x \ge right\) |

where \(\Lambda\) and \(\lambda\) are the cumulative distribution function and probability density function of the standard logistic distribution respectively, \(\mu\) is the location of the distribution, and \(\sigma\) the scale.

##### Value

`dclogis`

gives the density, `pclogis`

gives the distribution
function, `qclogis`

gives the quantile function, and `rclogis`

generates random deviates.
