Density, distribution function, quantile function, and random generation for the left and/or right censored logistic distribution.
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)
dclogis gives the density, pclogis gives the distribution
function, qclogis gives the quantile function, and rclogis
generates random deviates.
vector of quantiles.
vector of probabilities.
number of observations. If length(n) > 1, the length is
taken to be the number required.
location parameter.
scale parameter.
left censoring point.
right censoring point.
logical; if TRUE, probabilities p are given as log(p).
logical; if TRUE (default), probabilities are P[X <= x] otherwise, P[X > x].
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 \(x \ge right\) |
| \(\lambda((x - \mu)/\sigma)/\sigma\) | if \(left < x < right\) |
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.
