lndMvst computes the log of a Multivariate Student-t Density.
lndMvst
lndMvst(x, nu, mu, rooti,NORMC)
density ordinate
d.f. parameter
mu vector
inv of Cholesky root of \(\Sigma\)
include normalizing constant (def: FALSE)
log density value
This routine is a utility routine that does not check the input arguments for proper dimensions and type.
\(z\) \(\sim\) \(MVst(mu,nu,\Sigma)\)
