Density, distribution function, quantile function, and random generation
for the left and/or right censored student-t distribution with df
degrees of freedom.
dct(x, location = 0, scale = 1, df, left = -Inf, right = Inf, log = FALSE)pct(q, location = 0, scale = 1, df, left = -Inf, right = Inf,
lower.tail = TRUE, log.p = FALSE)
rct(n, location = 0, scale = 1, df, left = -Inf, right = Inf)
qct(p, location = 0, scale = 1, df, left = -Inf, right = Inf,
lower.tail = TRUE, log.p = FALSE)
dct
gives the density, pct
gives the distribution
function, qct
gives the quantile function, and rct
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.
degrees of freedom (> 0, maybe non-integer). df = Inf
is
allowed.
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 student-t distribution has density \(f(x)\):
\(T((left - \mu)/\sigma)\) | if \(x \le left\) |
\(1 - T((right - \mu)/\sigma)\) | if \(x \ge right\) |
\(\tau((x - \mu)/\sigma)/\sigma\) | if \(left < x < right\) |
where \(T\) and \(\tau\) are the cumulative distribution function
and probability density function of the student-t distribution with
df
degrees of freedom respectively, \(\mu\) is the location of the
distribution, and \(\sigma\) the scale.
