rmixture: Draw from Mixture of Normals

Description

rmixture simulates iid draws from a Multivariate Mixture of Normals

Usage

rmixture(n, pvec, comps)

Arguments

n

number of observations

pvec

ncomp x 1 vector of prior probabilities for each mixture component

comps

list of mixture component parameters

Value

A list containing …

x

An n x length(comps[[1]][[1]]) array of iid draws

z

A n x 1 vector of indicators of which component each draw is taken from

Warning

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

Details

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