lndIWishart: Compute Log of Inverted Wishart Density

Description

lndIWishart computes the log of an Inverted Wishart density.

Usage

lndIWishart(nu, V, IW)

Value

Log density value

Arguments

nu

d.f. parameter

V

"location" parameter

IW

ordinate for density evaluation

Warning

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

Author

Peter Rossi, Anderson School, UCLA, perossichi@gmail.com.

Details

\(Z\) \(\sim\) 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.
