The Shifted Log Normal Distribution

Density, distribution function, quantile function and random generation for the shifted log normal distribution with mean meanlog, standard deviation sdlog, and shift parameter shift.

pshifted_lnorm(
  q,
  meanlog = 0,
  sdlog = 1,
  shift = 0,
  lower.tail = TRUE,
  log.p = FALSE
)

  p,
  meanlog = 0,
  sdlog = 1,

)

rshifted_lnorm(n, meanlog = 0, sdlog = 1, shift = 0)

Arguments

x, q

Vector of quantiles.

meanlog

Vector of means.

sdlog

Vector of standard deviations.

shift

Vector of shifts.

log

Logical; If TRUE, values are returned on the log scale.

lower.tail

Logical; If TRUE (default), return P(X <= x). Else, return P(X > x) .

log.p

Logical; If TRUE, values are returned on the log scale.

p

Vector of probabilities.

n

Number of draws to sample from the distribution.
