lndMvn computes the log of a Multivariate Normal Density.
lndMvn
lndMvn(x, mu, rooti)
Log density value
density ordinate
mu vector
inv of upper triangular Cholesky root of \(\Sigma\)
This routine is a utility routine that does not check the input arguments for proper dimensions and type.

\(z\) \(\sim\) \(N(mu,\Sigma)\)

Sigma = matrix(c(1, 0.5, 0.5, 1), ncol=2) lndMvn(x=c(rep(0,2)), mu=c(rep(0,2)), rooti=backsolve(chol(Sigma),diag(2)))
