Description

This function calculates the density of the inverse gamma distribution.

Usage

Arguments

x	Input.
shape	Shape parameter.
scale	Scale parameter (1/rate).
log	Whether to return the log density.

Value

Returns the density (or log density).

Examples

# Draw samples from inverse gamma distribution with shape parameter 1 
# and scale parameter 1
samples = rinvgamma(100, shape=1, scale=1)

# Calculate density of samples
densities = dinvgamma(samples, shape=1, scale=1)
