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)
x |
array where ith column gives grid points for ith variable |
pvec |
vector of mixture component probabilites |
comps |
list of lists of components for normal mixture |
length(comps) | is the number of mixture components |
comps[[j]] | is a list of parameters of the jth component |
comps[[j]]$mu | is mean vector |
comps[[j]]$rooti | is the UL decomp of Σ^{-1} |
An array of the same dimension as grid with density values
This routine is a utility routine that does not check the input arguments for proper dimensions and type.
