In stm: Estimation of the Structural Topic Model
rmvnorm R Documentation
Draw from a Multivariate Normal
Description
A basic function for doing multivariate normal simulations
via the cholesky decomposition of the covariance matrix. Function
is based on one by Peter Hoff.
Usage
rmvnorm(n, mu, Sigma, chol.Sigma = chol(Sigma))
Arguments
n
number of draws
mu
the K-dimensional mean
Sigma
the K by K dimensional positive definite covariance matrix
chol.Sigma
the cholesky decomposition of the Sigma matrix.
Details
This is a pretty standard multivariate normal generator. It could
almost certainly be faster if we ported it over to RcppArmadillo
but it isn't used a ton at the moment.
