The Inverse Gamma Distribution

Density, distribution function, quantile function and random generation for the inverse gamma distribution with parameters a and b.

Usage

dinvgamma(x, a, b, log = FALSE)

pinvgamma(q, a, b)

qinvgamma(p, a, b)

rinvgamma(ndraws, a, b)

Arguments

x

vector of quantiles.

a

positive parameter.

b

positive parameter.

log

logical; if TRUE, densities are returned as logarithms.

q

vector of quantiles.

p

vector of probabilities.

ndraws

number of observations.

Value

dinvgamma gives the density, pinvgamma gives the distribution function, qinvgamma gives the quantile function, and rinvgamma generates random deviates.
