lndMvst: Compute Log of Multivariate Student-t Density

Description

lndMvst computes the log of a Multivariate Student-t Density.

Usage

lndMvst(x, nu, mu, rooti,NORMC)

Arguments

x

density ordinate

nu

d.f. parameter

mu

mu vector

rooti

inv of Cholesky root of \(\Sigma\)

NORMC

include normalizing constant (def: FALSE)

Value

log density value

Warning

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

Details

\(z\) \(\sim\) \(MVst(mu,nu,\Sigma)\)
