lndIWishart: Compute Log of Inverted Wishart Density

Description

lndIWishart computes the log of an Inverted Wishart density.

Usage

lndIWishart(nu, V, IW)

Arguments

nu

d.f. parameter

V

"location" parameter

IW

ordinate for density evaluation

Value

log density value

Warning

This routine is a utility routine that does not check the input arguments for proper dimensions and type.

Details

\(Z\) \(\sim\) Inverted Wishart(nu,V). in this parameterization, \(E[Z]=1/(nu-k-1) V\), V is a k x k matrix lndIWishart computes the complete log-density, including normalizing constants.
