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

Details

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

Value

Log density value

Warning

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