The Inverse Gaussian Distribution

Density, distribution function, and random generation for the inverse Gaussian distribution with location mu, and shape shape.

dinv_gaussian(x, mu = 1, shape = 1, log = FALSE)

pinv_gaussian(q, mu = 1, shape = 1, lower.tail = TRUE, log.p = FALSE)

rinv_gaussian(n, mu = 1, shape = 1)

Arguments

x, q

Vector of quantiles.

mu

Vector of locations.

shape

Vector of shapes.

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.

n

Number of draws to sample from the distribution.
