ptruncnorm: ptruncnorm .

Description

Cumulative distribution of the truncated normal function.

Usage

ptruncnorm(
  q,
  mean = 0,
  sd = 1,
  a = -Inf,
  b = Inf,
  lower.tail = TRUE,
  log.p = FALSE
)

Value

The distribution function of the truncated normal.

Invalid arguments will result in return value NaN with a warning.

Arguments

q

vector of quantiles,

mean

vector of means.

sd

vector of standard deviations.

a

vector of the left truncation value(s).

b

vector of the right truncation value(s).

lower.tail

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

log.p

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