mixDen
computes the marginal density for each dimension of a normal mixture at each of the points on a user-specifed grid.
mixDen(x, pvec, comps)
An array of the same dimension as grid with density values
array where \(i\)th column gives grid points for \(i\)th variable
vector of mixture component probabilites
list of lists of components for normal mixture
This routine is a utility routine that does not check the input arguments for proper dimensions and type.

length(comps) | is the number of mixture components |
comps[[j]] | is a list of parameters of the \(j\)th component |
comps[[j]]$mu | is mean vector |
comps[[j]]$rooti | is the UL decomp of \(\Sigma^{-1}\) |
