log_hiwishart_InvA_const: normalizing constant for a HyperInv-Wishart

In NonDecompGraph: NonDecomposable Graph

Description

Generates the normalizing constant "cons." for a HyperInv-Wishart

Usage

log_hiwishart_InvA_const(G, df, S)

Arguments

G	decomposed graph object
df	d.f.
S	covariance matrix

Details

Generates the normalizing constant "cons." for a HyperInv-Wishart(G,df,S). Nonsingular pdf is p(clique) = cons. |K|^{-(df+2|p|)/2} exp(-trace(inv(K) S)/2)
