rmixture simulates iid draws from a Multivariate Mixture of Normals
rmixture(n, pvec, comps)A list containing:
an \(n x\) length(comps[[1]][[1]]) array of iid draws
an \(n x 1\) vector of indicators of which component each draw is taken from
number of observations
\(ncomp x 1\) vector of prior probabilities for each mixture component
list of mixture component parameters
This routine is a utility routine that does not check the input arguments for proper dimensions and type.

comps is a list of length ncomp with ncomp = length(pvec).
comps[[j]][[1]] is mean vector for the \(j\)th component.
comps[[j]][[2]] is the inverse of the cholesky root of \(\Sigma\) for \(j\)th component
