cnorm | R Documentation |
Density, distribution function, quantile function, and random generation for the left and/or right censored normal distribution.
dcnorm(x, mean = 0, sd = 1, left = -Inf, right = Inf, log = FALSE) pcnorm(q, mean = 0, sd = 1, left = -Inf, right = Inf, lower.tail = TRUE, log.p = FALSE) qcnorm(p, mean = 0, sd = 1, left = -Inf, right = Inf, lower.tail = TRUE, log.p = FALSE) rcnorm(n, mean = 0, sd = 1, left = -Inf, right = Inf)
x, q |
vector of quantiles. |
p |
vector of probabilities. |
n |
number of observations. If |
mean |
vector of means. |
sd |
vector of standard deviations. |
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]. |
If mean
or sd
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 normal distribution has density f(x):
Φ((left - μ)/σ) | if x ≤ left |
1 - Φ((right - μ)/σ) | if x ≥ right |
φ((x - μ)/σ)/σ | if left < x < right |
where Φ and φ are the cumulative distribution function and probability density function of the standard normal distribution respectively, μ is the mean of the distribution, and σ the standard deviation.
dcnorm
gives the density, pcnorm
gives the distribution
function, qcnorm
gives the quantile function, and rcnorm
generates random deviates.
